Answer
$$(2.5,-1)$$
Work Step by Step
The coordinates $(x_{m},y_{m})$ of the midpoint of the segment joining the points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ are given by
$$x_{m}=\frac{x_{1}+x_{2}}{2}$$ and $$y_{m}=\frac{y_{1}+y_{2}}{2}.$$
Substitute $x_{1}=3$, $y_{1}=4$, $x_{2}=2$ and $y_{2}=-6:$
$$x_{m}=\frac{3+2}{2}=2.5$$ and $$y_{m}=\frac{4+(-6)}{2}=-1.$$
