The midpoint of a line segment with endpoints $(x_1, y_1, z_1)$ and $(x_2, y_2, z_2)$ is given by $\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}, \frac{z_1 + z_2}{2}\right)$. Applying this formula to the given points $(-5, 8, 9)$ and $(-8, 9, 2)$ yields the midpoint $\left(\frac{-5 - 8}{2}, \frac{8 + 9}{2}, \frac{9 + 2}{2}\right) = \left(\frac{-13}{2}, \frac{17}{2}, \frac{11}{2}\right)$.
