Harmonic mean between x and y is

Harmonic mean between two positive numbers x and y, The simplified formula is I.e. you need to double the product of x and y then divide it by the sum of x and y...~

Harmonic mean between x and y is

In maths, the harmonic mean between two numbers, say x and y is defined as :-

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.

[ H stands for harmonic mean ]
