Step-by-step explanation:

A = (-1,2)

B = (4,1)

C = (7,16)

D = (a,b)

AC is a diagonal and BD is a diagonal (taken in order)

so, we know that the diagonals bisect each other in parallelogram...so the diagonals are divided in ratio 1:1

So, let that intersection point be O (X,Y)

considering diagonal AC, applying mid point theorem

now, considering diagonal BD

therefore, the fourth vertex D
