Step-by-step explanation:
Given suppose value of 2 items is 5,find its harmonic mean
- So harmonic mean is given by harmonic mean = n / 1 / a1 + 1 / a2 + 1/a3 +…….+ 1/a^n
- Now given value of 2 items is 5 and we need to find the value of the harmonic mean.
- Value of n = 2 items. And so we get 2 / 1/5 + 1/5
- = 2 / 2 / 5
- = 10 / 2
- = 5
- So harmonic mean will be 5
