    The sequence is the a geometric sequence because the terms has a common ratio. the common ratio = - 80 / 200 = - 2 / 5common ratio = 32 / - 80 = - 2 / 5

    so the next to term can be solve multiplying the last term with the common ratio

    x = - 12.8 (-2 / 5) x = 5.12

    y = 5.12 ( - 2 / 5) y = - 2.048
