Harmonic mean between x and y is
In maths, the harmonic mean between two numbers, say x and y is defined as :-
[tex] \rightarrow \red{ \tt \frac{ H = 2 \times x \times y}{(x + y)} }[/tex]
For example, take two numbers 4 and 8 .
=> H = 2 × 4 × 8 / (4 + 8)
=> H = 64 / 12
=> H = 5.3333
So, this is how we calculate the harmonic mean of any two numbers.
