Geometric mean of $$$7$$$, $$$22$$$

Find the geometric mean of $$$7$$$, $$$22$$$.

The geometric mean of data is given by the formula $$$\left(\prod_{i=1}^{n} x_{i}\right)^{\frac{1}{n}}$$$, 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 product of the values is $$$\left(7\right)\cdot \left(22\right) = 154$$$.

Therefore, the geometric mean is $$$\sqrt{154}$$$.

The geometric mean is $$$\sqrt{154}\approx 12.409673645990857$$$A.
