Answer 1

B. 1/2, -1/8, 1/32

Explanation:

We know that since we have a negative common ratio, our terms in the sequence will alternate the sign. So we know that our second term is positive, third term is negative, and ultimately fourth term is positive.

We also know that 2/1 * 1/4 = 1/2

1/2 * -1/4 = -1/8

-1/8 * -1/4 = 1/32

Hope this helps
