About Geometric Sequence Calculator
This Geometric Sequence Calculator is used to calculate the nth term and the sum of the first n terms of a 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 a1 and the common ratio is r, then the nth term of the sequence is given by:
an = a1rn-1
