A sequence of numbers is said to be geometric if any term after the first can be obtained by multiplying the previous number by the same constant. This constant is called the common ratio. So the sequence 1,2,4,8,16 is geometric since each number in...

A series of numbers which increases by a constant, or common, ratio, e.g. 2, 4, 8, 16, where 2 is the common ratio. MALTHUS asserted that population grows according to this progression. See also: arithmetic...

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 fixed non-zero number called the common ratio. For example, the sequence...
