Suppose that three consecutive whole numbers are :
First number = x
Second Number = x+1
Third Number = x+2
Given that sum of 3 numbers is 57
x + (x + 1) + (x + 2) = 57
x + x + 1 + x + 2 = 57
3x + 3 = 57
3x = 54
x = 18
So, first whole number x = 18
second whole number = x+1 = 18 + 1 = 19
third whole number = x +2 = 18 + 2 = 20
Final answer is : 18, 19, 20
x + x + 1 + x + 2 = 57
3x + 3 = 57
3x = 54
x = 18
So the numbers are 18, 19 and 20.
