See explanation.

Explanation:

The coordinates of a midpoint of a line segment are the average of coordinates of its ends:

${y}_{M} = \frac{{y}_{A} + {y}_{B}}{2}$

if the points were located in a 3D space you would have to add the third coordinate:

${z}_{M} = \frac{{z}_{A} + {z}_{B}}{2}$

So in the given example we have:

M=((3+2)/2;(-17+(-8))/2)

Answer: M=(5/2;-25/2)
