Velocity at the midpoint under constant acceleration

A particle moves along a straight line with constant acceleration. It passes through a point $A$ with velocity $u$ m s $^{-1}$ and then through a point $B$ with velocity $v$ m s $^{-1}$ .

The velocity of the particle at the midpoint of the line segment $AB$ is given by
