Question

Write the first four terms of the sequence whose explicit formula is An = 2^n. *

Answer 1

2, 4, 8, 16

Explanation:

`A_n = 2^n \\ plug \: n = 1, \: 2, \: 3, \: 4 \\ A_1 = 2^1 = 2 \\ A_2 = 2^2 = 4 \\ A_3= 2^3 = 8 \\ A_4 = 2^4 = 16 \\`

Hence, first four terms of the given sequence are 2, 4, 8, 16.
