Answer:
![a_2 = 8](https://tex.z-dn.net/?f=a_2%20%3D%208)
![a_3 = 18](https://tex.z-dn.net/?f=a_3%20%3D%2018)
![a_4 = 38](https://tex.z-dn.net/?f=a_4%20%3D%2038)
Step-by-step explanation:
We are given the following recursive formula:
![a_n = 2(a_{n-1}+1)](https://tex.z-dn.net/?f=a_n%20%3D%202%28a_%7Bn-1%7D%2B1%29)
And consider ![a_1 = 3](https://tex.z-dn.net/?f=a_1%20%3D%203)
a2
![a_2 = 2(a_1 + 1) = 2(3 + 1) = 8](https://tex.z-dn.net/?f=a_2%20%3D%202%28a_1%20%2B%201%29%20%3D%202%283%20%2B%201%29%20%3D%208)
a3
![a_3 = 2(a_2 + 1) = 2(8 + 1) = 18](https://tex.z-dn.net/?f=a_3%20%3D%202%28a_2%20%2B%201%29%20%3D%202%288%20%2B%201%29%20%3D%2018)
a4
![a_4 = 2(a_3 + 1) = 2(18 + 1) = 38](https://tex.z-dn.net/?f=a_4%20%3D%202%28a_3%20%2B%201%29%20%3D%202%2818%20%2B%201%29%20%3D%2038)
