Harmonic mean of $22$, $30$

Find the harmonic mean of $22$, $30$.

The harmonic mean of data is given by the formula $H = \frac{n}{\sum_{i=1}^{n} \frac{1}{x_{i}}}$, where $n$ is the number of values and $x_i, i=\overline{1..n}$ are the values themselves.

Since we have $2$ points, $n = 2$.

The sum of the reciprocals of the values is $\frac{1}{22} + \frac{1}{30} = \frac{13}{165}$.

Therefore, the harmonic mean is $H = \frac{2}{\frac{13}{165}} = \frac{330}{13}$.

The harmonic mean is $\frac{330}{13}\approx 25.384615384615385$A.
