An odd integer can be represented by the expression 2n+1 wherein is any integer find 3 consecutive odd integers that have a sum of - 51

easiest way to calculate that is:

-51/3 = - 17

now add 2 to - 17 (-17 + 2 = - 15)

subtract 2 from - 17 (-17-2 = - 19)

the 3 consecutive odd numbers are - 15, - 17, - 19

-15 + - 17 + - 19 = - 51
