Answer provided by our tutors

the two consecutive positive odd integers can be written as


2x-1 and 2x+1, where x is positive integer


the product of two consecutive positive odd integers is equal to 1 less than seven times the sum of the integers


(2x - 1)(2x + 1) = 7(2x - 1 + 2x + 1) - 1


by solving we find and consider the positive roots


x = 7
