In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a common ratio. We determine the ratio as follows:
r = 11.304 / 2.512 = 4.5 r = 50.868 / 11.304 = 4.5 r = 228.906 / 50.868 = 4.5
