Meaning and Definition
The constant ratio between successive terms in a geometric sequence (e.g., each term is multiplied by a fixed number to get the next).
Any proportional relationship exhibiting constant multiplicative growth or decay; often used metaphorically to describe situations with exponential scaling.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or definitional differences. In older British texts, 'common ratio' is slightly more frequent, while American texts may use 'geometric ratio' and 'common ratio' equally.
Connotations
Identical in both varieties. Connotes mathematical precision and exponential processes.
Frequency
Low frequency in general discourse, but standard in technical/mathematical contexts in both regions.

Frequently Asked Questions
Yes, in the context of a geometric sequence/progression, they are synonymous terms.
Yes. If the ratio is between 0 and 1, it describes a decaying geometric sequence (e.g., 16, 8, 4, 2 has a ratio of 0.5).
Rarely. It is a precise technical term. In broader contexts, people use 'exponential growth rate' or 'multiplying factor'.
Divide any term in the geometric sequence by the term immediately preceding it.
