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
