### Your Input

**Find the harmonic mean of $$$13$$$, $$$14$$$.**

### Solution

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 $$$\frac{1}{13} + \frac{1}{14} = \frac{27}{182}$$$.

Therefore, the harmonic mean is $$$H = \frac{2}{\frac{27}{182}} = \frac{364}{27}$$$.

### Answer

**The harmonic mean is $$$\frac{364}{27}\approx 13.481481481481481$$$A.**
