This online Geometric Sequence Calculator is used to calculate the nth term and the sum of the first n terms of geometric sequence.

## Geometric Sequence

In mathematics, a geometric sequence, also known as a geometric progression, 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. The sum of the numbers in a geometric progression is also known as a geometric series.

If the initial term of a geometric sequence is a_{1} and the common ratio is *r*, then the nth term of the sequence is given by:
