The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
Step-by-step explanation:
The statement describes an arithmetic progression, which is defined by following formula:
[tex]p(n) = p_{1}+r\cdot (n-1)[/tex] (1)
Where:
[tex]p_{1}[/tex] - First element of the sequence.
[tex]r[/tex] - Progression rate.
[tex]n[/tex] - Index of the n-th element of the sequence.
[tex]p(n)[/tex] - n-th element of the series.
If we know that [tex]p_{1} = 1[/tex], [tex]n = 2[/tex] and [tex]p(n) = 5[/tex], then the progression rate is:
[tex]r = \frac{p(n)-p_{1}}{n-1}[/tex]
[tex]r = 4[/tex]
The set of elements of the series are described by [tex]p(n) = 1 + 4\cdot (n-1)[/tex].
Lastly, if we know that [tex]n = 300[/tex], then the 300th term of the sequence is:
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 1197[/tex]
And the next three terms of the sequence are:
n = 5
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 17[/tex]
n = 6

[tex]p(n) = 21[/tex]
n = 7
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 25[/tex]

First of all, a journey refers to traveling from one place to another. When it comes to journeys, train journeys take the top spot. A train journey certainly is a wonderfully joyous occasion. Furthermore, train journeys fill individuals with a feeling of intense excitement. This mode of the journey is best when the travel distance is long. A train journey creates an aura that cannot be experienced with other types of journeys.
My Experience of Journey by Train
I have always been an avid supporter of train journeys. My involvement with train journeys began in childhood. I live in Lucknow and from here I have undertaken many train journeys. Furthermore, since childhood, I have paid several visits to the hill station of Almora to meet my relatives. Almora is a hill station located in the state of Uttarakhand. Most noteworthy, Almora is situated in the Himalayan mountain region. Due to this, trains cannot travel directly to Almora. Consequently, Kathgodam is the last town station accessible by trains before the mountain range begins.
The trip from Lucknow to kathgodam is quite a lively experience. I have always ensured the reservation of my seats beforehand. So, my train journey begins from Lucknow railway station. As the train undergoes motion and leaves the Lucknow railway station, my excitement begins to rise. Moreover, as the train gathers speed, a thrilling feeling overtakes me.
My train journey from Lucknow to Kathgodam is probably 8-10 hours duration. However, I enjoy every minute of it in spite of the journey being so long. Furthermore, all along the journey, one can purchase items of food and drinks. I almost always purchase meals and refreshments at least twice in the journey.
When slumber overtakes me, I make use of the sleeping berth. I personally find sleeping on the train berth very comfortable. When I wake after a deep sleep, mountains are visible from a distance. Moreover, as the train approaches Kathgodam with menacing speed, the view of mountains gets bigger and bigger. Also, my amusement greatly rises as I see the Himalayas draw closer. Finally, as the train stops at Kathgodam, my delightful train journey comes to an end.
Why Do I Like to Travel by Train?
Comfort is one of the biggest advantages of a train journey. Most noteworthy, one can move freely in a train cabin. Furthermore, in trains, there is a possibility of an ample foot room. Moreover, trains offer comfortable sleeping berths. All of this makes the train journey a relaxing experience.
Beautiful sightseeing is another noteworthy benefit of train journeys. As the train travels, one can enjoy the views of the countryside, farms, forests, factories, etc. This makes train journeys more comprehensive than journeys by air or road.
Train journeys offer a variety of opportunities to pass time. Furthermore, the train offers a sociable environment. In train journeys, conversations between passengers almost always take place. One can make new friends with traveling passengers on the train easily. Also, one can spend time in a handsome manner on a train journey. In a train journey, one can spend time reading something, listening to music, watching videos, sleeping/resting comfortably, etc.
To sum it up, train journeys are truly one of a kind. The train journey offers uniqueness like no other journey. Most noteworthy, the charm of such a journey is unmatchable. The train journey certainly offers an unforgettable rich experience.

Two boats start their journey from the same point A and travel along directions AC and AD, as shown below:
What is the distance, CD, between the boats?
230.9 ft
284.3 ft
115.5 ft
173.2 ft
Answers
Answer:
Option (1)
Step-by-step explanation:
By applying tangent rule in ΔABD,
tan(30°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{AB}{BD}[/tex]
BD = [tex]\frac{AD}{\text{tan}(30)}[/tex]
BD = [tex]\frac{200}{\frac{1}{\sqrt{3} } }[/tex]
BD = 200√3 ft
By applying tangent rule in ΔABC,
tan(60°) = [tex]\frac{AB}{BC}[/tex]
[tex]\sqrt{3}=\frac{200}{BC}[/tex]
BC = [tex]\frac{200}{\sqrt{3}}[/tex]
Since, CD = BD - BC
CD = 200√3 - [tex]\frac{200}{\sqrt{3}}[/tex]
= 346.41 - 115.47
= 230.94 ft
≈ 230.9 ft
Therefore, Option (1) will be the correct option.

B) debemos saber representar las gráficas de las rectas. Nosotros lo haremos uniendo puntos calculados previamente. Terminaremos con un sistema de dos inecuaciones (o desigualdades). En este caso, la solución del sistema es la intersección de dos regiones del plano.
C) es un método lineal ya que no se basa en despejes, se utilizan procesos algebraicos estructurados.
D) consiste en despejar o aislar una de las incógnitas (por ejemplo, x ) y sustituir su expresión en la otra ecuación. De este modo, obtendremos una ecuación de primer grado con la otra incógnita, y . Una vez resuelta, calculamos el valor de x sustituyendo el valor de y que ya conocemos.

Answers
Answer:
El método de igualación consiste en despejar la misma incógnita en las dos ecuaciones y después igualar los resultados.
Los pasos a seguir son los siguientes:
sistema de ecuaciones
En primer lugar, elegimos la incógnita que deseamos despejar. En este caso, empezaré por la «x» y despejo la misma en ambas ecuaciones.
x+y=7; x=7-y
5x-2y=-7; 5x=2y-7
x=(2y-7)/5
Una vez hemos despejado, igualamos:
7-y = (2y-7)/5
5.( 7-y) = (2y -7)
35 -5y= +2y -7
42=7y
y=42/7=6
y=6
Por último, sustituimos el valor que hemos calculado despejando la otra incógnita en una de las ecuaciones iniciales.

Answers
The value of the x and y by the elimination method will be 2 and 1.
What exactly is a linear system?It is an equation system in which the maximum power of the variable is always 1. A figure with only one dimension and no breadth. It is made up of infinite dots placed side by side.
Given linear equation;
3x+ 4y= 10
2x- 2y = 2
The following operations are done;
(3x+ 4y= 10) ×2
(2x- 2y = 2) × 3
6x+8y=20
6x-6y=6
Subtract equation 1 from 2 to eliminate x;
6x+8y-6x+6y=20-6
14y=14
y=1
The value of x is obtained by putting the value in equation 1;
3x+4(1)=10
3x=6
x=2
Hence, the value of the x and y by the elimination method will be 2 and 1.

By triangle sum theorem,
Sum of all angles of a triangle is 180°.
m∠1 + m∠2 + m∠3 = 180°
(m∠1 + m∠3) + m∠2 = 180°
2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]

We were told to use 7 and 12 to equal 84. Let's try 12 in the first bracket and 7 in the second:
(2x 12)(x 7): (2x)(7) and (12)(x) = 14x and 12x, which we cant make 17x from
Now let's try 7 in the first bracket and 12 in the second:
(2x 7)(x 12): (2x)(12) and (7)(x) = 24x and 7x, which we CAN use to make 17x if the 7x is negative, ie place a '+' before the twelve in the second bracket and a '-' before the seven in the first bracket.
(2x-7)(x+12)
Double check: (2x-7)(x+12)=2x(x+12)-7(x+12)=2x²+24x-7x-84=2x²+17x-84

brainliest is appreciated
Answer:
1.6
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
98+92+96+97+97=480
480/5 values=96 is the mean or average of the set of numbers
so we just find the absolute value of the data value minus the mean.
For the first one it would be |98-96|=2
then continue on and get a set of values
{2,4,0,1,1}
now find the average of that to get the mean absolute deviation
2+4+0+1+1=8
