My strategy was to calculate AB, then take 1/3 of this and add it to the position vector for B. However this returns the incorrect answer.The position vectors of the points A and B relative to an origin O are 5i + 4j + k, -i + j - 2k respectively. Find the position vector of the point P which lies on AB produced such that AP=2BP.
Did you make a sketch?The position vectors of points and relative to an origin
Find the position vector of point which lies on produced so that:

Code:: ← - - - - 2 - - - - → : *-----------*-----------* A B ← - 1 - → P
As you can see, is the midpoint of
