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