Find Vector u Midpoint (-2,-4,0) to (10,6,0) and (1,-4,4) to (5,8,-10)

[~Sam~]

Homework Statement

Find the vector u=(xyz) whose

(i) initial point is the midpoint of (-2,-4,0) and (10,6,0)

(ii) terminal point is the midpoint of (1,-4,4) and (5,8,-10)

Homework Equations

I know the midpoint for two vectors from say..P to Q is P+ (1/2) (Q1-P1 Q2-P2, Q3-P3)

The Attempt at a Solution

I can find mids for both..but am confused by the initial midpoint to terminal midpoint..what else do I need?

i think read start & end of the vector u, for initial & terminal respectively. The midpoint just let's you find where they are
