What is geometric mean? – Definition and formula
The geometric mean is a type of average. It indicates the central tendency of a set of values by using the product of the numbers in the set. To calculate it, we need to find the nth root of the product. n is the number of values inside the set.

To better understand the geometric mean, we need to know what a geometric sequence is. A geometric sequence or a geometric progression is a specific set of numbers, where every number after the first one, can be calculated by multiplying the previous one by a non-zero number, called the common ratio.
