Selina Finley · Answer 1

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
