The fixed multiplier used to obtain each term of a geometric progression from the preceding term.

The fixed multiplier between consecutive terms of a geometric progression, found by dividing a term by the preceding non-zero term.

The constant multiplier that takes one term of a geometric sequence to the next.

A surd can also be the common ratio.

When working backwards, reverse the operation: subtract the common difference or divide by the common ratio.

Keep surds in exact form. Decimal approximations can hide an exact common ratio and introduce rounding errors.
