r = first number
r + 1 = second number
r + 2 = third number
r + r + 1 + r + 2 = 144
3 r + 3 = 144 Subtract 3 To both sides
3 r + 3 - 3 = 144 - 3
3 r = 141 Divide both sides by 3
r = 141 / 3 = 47
r + 1 = 48
r + 2 = 49
47 + 48 + 49 = 144
r + 1 = second number
r + 2 = third number
r + r + 1 + r + 2 = 144
3 r + 3 = 144 Subtract 3 To both sides
3 r + 3 - 3 = 144 - 3
3 r = 141 Divide both sides by 3
r = 141 / 3 = 47
r + 1 = 48
r + 2 = 49
47 + 48 + 49 = 144
