Geometric series
The geometric
series a
+ ar + ar2 + ar3 + ar4 + ··· is
determined by its initial term
a
and its ratio
r.
If
|r|
< 1,
the series converges to
.
If
|r|
≥ 1
and
a ≠ 0,
it diverges.
The sequence a, ar, ar2, ar3, ar4, ··· is called a geometric progression. Each term is a fixed multiple of the previous term.
