Use the mid-point formula. See below:

Explanation:

The equation to find the mid-point of a line segment give the two end points is:

$M = \frac{\textcolor{red}{{x}_{1}} + \textcolor{b l u e}{{x}_{2}}}{2}$

Substituting the two points gives:

$M = \frac{\textcolor{red}{- 7} + \textcolor{b l u e}{4}}{2}$

$M = - \frac{3}{2}$ or $M = - 1.5$
