What are the next three terms of the geometric sequence 32, - 16, 8, ...?

a.

2, 1, 1/2

c.

-8, 16, - 32

b.

4, 2, 1

d.

-4, 2, - 1

To find the common ratio, divide the 2nd term by the first term

-16 / 32 = - 0.5 ... this means u multiply each number by - 0.5 to find the next number

8 * - 0.5 = - 4 <==

-4 * - 0.5 = 2 <==

2 * - 0.5 = - 1 <==

answer D
