A geometric series is an infinite series whose terms have a common ratio or are in a geometric progression. A Geometric Progression (GP) is formed by multiplying a starting number (a 1) by a number r, called the common ratio. In this sequence, the next term is obtained by multiplying a constant term to the previous term and the previous term can be obtained by dividing a constant term into the term. This ratio, r, is called the common ratio of the geometric sequence. Geometric Sequence Calculator. The first three terms of a geometric progression are 2 x, 4 x + 14 and 20 x - 14.
