The formula is a^2-b^2=(a-b)(a+b)
So answer is (5x-3)(5x+3)
It would be B
It wouldn't be A, C or D because...

Since they are 6 consecutive even numbers, they will alternate odd/even/odd/even.
x, x+2, x+4, x+6, x+8, x+10 = 126
Simplify
6x + 30 = 126
6x = 96
x = 16
And you want the fourth number, so plug the x value back into the equation of 'x+6' and you will get 16+6 which = 22.
