Geometric Sequence

Pronunciation: /ˌdʒi əˈmɛt rɪk ˈsik wəns/ Explain

A geometric sequence is a sequence of numbers with a common ratio.

For example, the geometric sequence { 1, 3, 9, 27, ... } has a common ratio of 3, since 1·3 = 3, 3·3 = 3, and 9·3 = 27.

A geometric sequence is also called a geometric progression. A geometric sequence is the same thing as a geometric progression.
