Odd numbers are every other number. So, the expression for the consecutive odd numbers is x, x+2, x+4. To determine x, write out the expressions as an algebraic equation:
(sum of the first two) (is) (five less than three times the third)
x + (x + 2) = 3 * (x + 4) - 5
2x + 2 = 3x + 12 - 5
2x + 2 = 3x + 7
(2x - 3x) = 7 - 2
-x = 5
So, x = -5 and the 3 consecutive numbers are:
-5, -3, and -1.
