The standard deviation of $$n$$ numbers $$x_{1}$$, $$x_{2}$$, $$x_{3}$$,......, $$x_{n}$$, with mean $$\overline{x}$$ is equal to $$\sqrt{\frac{s}{n}}$$, where $$S$$ is the sum of the squared differences $$(x_{i} - \overline{x})^{2}$$ for 1 ≤ i ≤ n.
For what value of $$x$$ is the standard deviation of the numbers $$6$$, $$14$$, $$16$$, and $$x$$ least?
