What is the Geometric Sequence Calculator?
A geometric sequence multiplies by the same number (the common ratio r) each time, like 3, 6, 12, 24. Enter a₁, r and n to get the nth term, the sum of n terms, and the sum to infinity when |r| < 1.
How to use the Geometric Sequence Calculator
- Enter a₁, r and n.
- Read aₙ, Sₙ and the sum to infinity.
When does a GP have a sum to infinity?
Only when the ratio is between -1 and 1. Then S∞ = a₁ / (1 - r).
This Geometric Sequence Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
