If x = (y)(y + 1) and y is a prime number less than 11, which of the following could not be the product of 2 consecutive integers?
Choose the correct choice from the following options.
A) 5x	B) 11x	C) 13x	D) 23x	E) 57x
Given y is a prime number less than 7   so y can be 2 3 5 7   x=y*(y+1)   so x can be 6 12 30 56   So from options   A. 5x can be (5*6)   B. 11x can be (11*12)   C. 13x can be (13*12)   D. 23x cannot be   E. 57x can be (56*57)   So answer option 23x.
