Let
$V_1$$=$ $\frac{7^2\:+\:8^2\:+\:15^2+23^2}{4} -\left(\frac{7\:+\:8\:+\:15\:+\:23}{4}\right)^2$ $,$ $$$$ $V_2$$=$ $\frac{6^2\:+\:8^2\:+\:15^2+24^2}{4}-\left(\frac{6\:+\:8\:+\:15\:+\:24}{4}\right)^2$ $,$ $$$$ $V_3$$=$ $\frac{5^2\:+\:8^2\:+\:15^2+25^2}{4}-\left(\frac{5\:+\:8\:+\:15\:+\:25}{4}\right)^2$ $,$ $$$$
Then
$(A) V_3<V_2<V_1$
$(A) V_3<V_1<V_2$
$(A) V_1<V_2<V_3$
$(A) V_2<V_3<V_1$
Whichever follows ?
