# Ratio (in Geometric Sequence)

## Ratio (in Geometric Sequence)

In a geometric sequence, the ratio is a constant number that makes it possible to find each term in the sequence based on the preceding term.

### Example

In the geometric sequence 10, 20, 40, 80, 160, 320, …, the rule ×2 is the constant ratio between a term and the one that precedes it.
