Geometric Mean

In mathematics, the geometric mean is a mean or average, which is defined as the nth root of the product of n numbers.

$$\bar{a}=\sqrt[n]{a_{1}\times a_{2}\times ...\times a_{n}}$$


a1, ...ā€” set of values;
nā€” the number of values.

Arithmetic mean of two values is always greater than geometric mean of the same values.
