Geometric Sequence
Pronunciation: /ˌdʒi.əˈmɛt.rɪk ˈsi.kwəns/ 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 = 9, and
9 · 3 = 27.
A geometric sequence is also called a
geometric progression.
A geometric sequence is the same thing as a geometric progression.
