Common ratio
01
共通比, 一定比
the constant ratio between consecutive terms
例
In the geometric sequence 2, 6, 18, 54, ..., the common ratio between consecutive terms is r=3.
幾何学的数列 2, 6, 18, 54, ... において、連続する項間の共通比は r=3 です。
The common ratio of a geometric sequence can be negative, indicating alternating signs between consecutive terms.
幾何数列の共通比は負になることがあり、連続する項の間で符号が交互に変わることを示します。
