Geometric

A geometric sequence is a sequence that has a common multiplier between terms. This ratio is constant and is called the common ratio, r. The difference between consecutive terms in a geometric sequence varies, unlike an arithmetic sequence.

An example of a geometric sequence is 1, 2, 4, 8, 16 … and the common ratio of this sequence is 2. To change from one term to the next in the sequence, multiply by two.
