Question

write the first three terms of sequence whose nth term is an =2^n​

Answer 1

ANSWER.

• The first three terms of the sequence are - 2, 4 and 8.

SOLUTION.

Here, the nth term of the sequence is calculated using the formula - 2ⁿ

We assume that n ∈ N. So, n is a set of natural numbers.

First three terms are as follows,

> 2¹ = 2

> 2² = 4

> 2³ = 8

So, the first three terms we get from this sequence are - 2, 4 and 8.
