Question

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.

Does the series converge or diverge? If it converges, what is the sum? Show your work.

Answer 1

Explanation:

This is a geometric series where our common ratio is -1/2, and a is -4

Since r is less than -1, this series converges so

The sun is

`( - 4)/(1 + 0.5)`

`( - 4)/(1.5) = - (8)/(3)`

The sum is -8)3
