Answer:

1/4, -1/8, and 1/16

Step-by-step explanation:

Geometric sequence: -2, 1, -1/2, ....

Geometric sequence means there is a common ratio.

so from -2 , the next term is -2*r , and the next term is -2*r*r

-2r = 1, means r = -1/2

then next after -1/2, is 1/4,

and then... -1/8, and then 1/16
