See explanation.

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

$x_M=(x_A+x_B)/2$

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

So in the given example we have:

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

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