    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
