# What is the midpoint between the points (3, 1) and (1, 5)?

The midpoint of two points $A \left({x}_{1} , {y}_{1}\right)$ and $B \left({x}_{1} , {y}_{1}\right)$ is
$M \left(\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}\right)$
so for points $\left(3 , 1\right)$ and $\left(1 , 5\right)$ it is
$\left(\frac{3 + 1}{2} , \frac{1 + 5}{2}\right) = \left(2 , 3\right)$
