The reciprocal of the harmonic mean of n numbers is the arithmetic mean of their reciprocals. Harmonic mean of various items of a series is the reciprocal of the arithmetic mean of their reciprocals.

Symbolically,

$Harmonic\ mean = \frac{N}{\frac{1}{X_{1}} + \frac{1}{X_{2}}....\frac{1}{X_{n}}}$

$Harmonic\ mean = \frac{N}{\frac{1}{X_{1}} + \frac{1}{X_{2}}....\frac{1}{X_{n}}}$

Where

- X
_{1}, X_{2}...X_{n}refer to the value of various items of the series. - N = Total number of items of the series.
