The consecutive integers are 12 , 13 ,14, and 15 .
Of the four consecutive integers let us consider the smallest integer be x.
Therefore the other 3 integers are x+1 , x+2 and x+3 .
Therefore the sum of the integers are:
x +(x+1)+(x+2)+(x+3)=4x+6
The sum of the integers is given 54.
∴4x + 6 = 54
or, 4x = 54 - 6
or, 4x = 48
or, x = 48 ÷ 4
or, x = 12
Therefore the three other integers are 13,14 and 15.
