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

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 consecutiveodd integer number are - 15 , - 17 , - 19

if you procede the sum is - 51
