{wiki=Geometric–harmonic_mean}
The geometric-harmonic mean is a type of mean that combines features of both the geometric mean and the harmonic mean. Specifically, it is the mean of two numbers calculated through a two-step process involving these two types of means. 1. **Geometric Mean (GM)**: For two positive numbers \\( a \\) and \\( b \\), the geometric mean is given by: \\\[ GM = \\sqrt\{ab\} \\\] 2.
