#### Answer

$\left( 4.65,-1 \right)$

#### Work Step by Step

Using $\left( \dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2} \right)$ or the Midpoint Formula, the midpoint of the segment joining $\left(
4.1,6.9
\right) \text{ and } \left(
5.2,-8.9
\right),$ is
\begin{array}{l}\require{cancel}
\left( \dfrac{4.1+5.2}{2},\dfrac{6.9+(-8.9)}{2} \right)
\\\\=
\left( \dfrac{9.3}{2},\dfrac{-2}{2} \right)
\\\\=
\left( 4.65,-1 \right)
.\end{array}
