Question

Find three consecutive odd integers with a sum of -51.

Answer 1

an odd integer number is defined by 2x - 1 so the next is 2x + 1  and the other is 2x + 3  the sum of the three number is - 51

( 2x - 1 ) + ( 2x + 1) + ( 2x + 3 ) = - 51    we solve pharenthesis
2x - 1 + 2x + 1 + 2x + 3 = - 51
6x + 3 = - 51
6x = - 51 - 3
6x = - 54 
x = - 54 / 6
x = - 9

so  2x - 1 = 2 ( - 9 ) - 1 = - 18 - 1 = - 19
      2x + 1 = 2 ( - 9 ) + 1 = - 18 + 1 = - 17
      2x + 3 = 2 ( - 9 ) + 3 = - 18 + 3 = - 15

The three consecutive odd integer number are  - 15 , - 17 , -19
if you procede the sum is - 51
