Question

B(n) = -1 (2)^n-1 What is the 5th term in the sequence?

Answer 1

The answer is - 16

Explanation:

`b(n) = - 1 ({2})^(n - 1)`

where

n is the number of terms

From the question since we are finding the 5th term

n = 5

Substitute the value into the above formula and solve

We have

`b(5) = - 1({2})^(5 - 1) \\ = - 2 ^(4)`

We have the final answer as

- 16
