    Geometric sequences are:

    -1, 2.5, - 6.25, 15,625, ...

    8, 0.8, 0.08, 0.008, ...

    Geometric sequence is a sequence of numbers term after the first term is found by multiplying the previous term by a common ratio - - a fixed, none-zero number.

    -1 * - 2.5 = 2.5

    2.5 * - 2.5 = - 6.25

    -6.25 * - 2.5 = 15.625

    8 * 0.10 = 0.8

    0.8 * 0.10 = 0.08

    0.08 * 0.10 = 0.008
