In mathematics, a geometric progression, also known as a geometric sequence, 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. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3.
For a geometric sequence or geometric series, the common ratio is the ratio of a term to the previous term. This ratio is usually indicated by the variable r.
The constant factor between consecutive terms of a geometric sequence is called the common ratio.
The common ratio is the ratio between two numbers in a geometric sequence. Keep reading for a detailed definition, the formula for determining the...

Sometimes we are asked to find the common ratio of a certain geometric progression, and then use this to find a group of terms or simply a specific term.
To find the common ratio, I have to divide a successive pair of terms. It doesn't matter which pair I pick, as long as they're right next to each other. To be thorough ...
We deal with varies terms like common ratio, common distance, first term, n-th term etc. In geometric series or sequence, the common ratio is the ratio of a term to ...
