Arithmetic progressions product difference
Consider two sets A and B, each containing three numbers in A.P. Let the sum and the product of the elements of A be 36 and p respectively and the sum and the product of the elements of B be 36 and q respectively. Let d and D be the common differences of AP’s in A and B respectively such that D = d + 3, d > 0. If

=

, then p – q is equal to :
