Question

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

Answer 1

Answer:

The answer is - 16

Step-by-step 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
