B) $( - 7,5,22 )$
C) $( - 7,22,5 )$

Quizplus · Accepted Answer

The midpoint formula for a line segment with endpoints $(x_1, y_1, z_1)$ and $(x_2, y_2, z_2)$ is $\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}, \frac{z_1 + z_2}{2}\right)$. Applying this to the given points, the midpoint is $\left(\frac{-20 + 6}{2}, \frac{20 + 24}{2}, \frac{3 + 7}{2}\right) = (-7, 22, 5)$.
