The sum of four consecutive whole numbers is 54, what are the four numbers

Let the four consecutive numbers be x, x+1, x+2, and x+3.

The sum of the four numbers is 54, therefore

x + (x+1) + (x+2) + (x+3) = 54

4x + 6 = 54

4x = 54 - 6 = 48

x = 12

Answer:

The four numbers are 12, 13, 14, and 15
