Step-by-step explanation:
The first five terms of the sequence are 1, 4, 7, 10, 13.
Solution:
Given data:
![a_{1}=1](https://tex.z-dn.net/?f=a_%7B1%7D%3D1)
![a_{n}=a_{n-1}+3](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7Bn-1%7D%2B3)
General term of the arithmetic sequence.
, where d is the common difference.
d = 3
![a_{n}=a_{n-1}+3](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7Bn-1%7D%2B3)
Put n = 2 in
, we get
![a_{2}=a_1+3](https://tex.z-dn.net/?f=a_%7B2%7D%3Da_1%2B3)
![a_{2}=1+3](https://tex.z-dn.net/?f=a_%7B2%7D%3D1%2B3)
![a_2=4](https://tex.z-dn.net/?f=a_2%3D4)
Put n = 3 in
, we get
![a_{3}=a_2+3](https://tex.z-dn.net/?f=a_%7B3%7D%3Da_2%2B3)
![a_{3}=4+3](https://tex.z-dn.net/?f=a_%7B3%7D%3D4%2B3)
![a_3=7](https://tex.z-dn.net/?f=a_3%3D7)
Put n = 4 in
, we get
![a_{4}=a_3+3](https://tex.z-dn.net/?f=a_%7B4%7D%3Da_3%2B3)
![a_{4}=7+3](https://tex.z-dn.net/?f=a_%7B4%7D%3D7%2B3)
![a_4=10](https://tex.z-dn.net/?f=a_4%3D10)
Put n = 5 in
, we get
![a_{5}=a_4+3](https://tex.z-dn.net/?f=a_%7B5%7D%3Da_4%2B3)
![a_{5}=10+3](https://tex.z-dn.net/?f=a_%7B5%7D%3D10%2B3)
![a_5=13](https://tex.z-dn.net/?f=a_5%3D13)
The first five terms of the sequence are 1, 4, 7, 10, 13.
