This category contains results about Geometric Progressions.
Definitions specific to this category can be found in Definitions/Geometric Progressions.


A geometric progression is a sequence $\left \langle{x_n}\right \rangle$ in $\R$ defined as:

$x_n = a r^n$ for $n = 0, 1, 2, 3, \ldots$


Thus its general form is:

$a, ar, ar^2, ar^3, \ldots$

and the general term can be defined recursively as:

$x_n = \begin{cases} a & : n = 0 \\ r x_n & : n > 0 \\ \end{cases}$
