The sum of three consecutive numbers is twelve less than six times the lowest number. The three numbers are 5 , 6 ,7 .

Let the lowest number is x , 2nd number is x + 1 , 3th number is x + 2,

x + x + 1 + x + 2 = 6x - 12

3x + 3 = 6x - 12

-3x = -15

x = 5

x + 1 = 5 + 1 = 6

x + 2 = 5 + 2 = 7

The three number are 5 , 6 , 7.
