Find parametric equations for the line that passes through the point (0,-1,1) and the midpoint of the line segment from (2,3,-2) to (4,-1,5).

This is my work below. Can someone confirm to see if I have the correct answer? There is no answer in the back for this question. Please let me know. Thanks for your help.

m=(3,1,1.5)

d=(3,2,0.5)

x=3t

y=-1+2t

z=1+0.5t
