Answer:
The numbers 12, 13, 14, and 15.
Step-by-step explanation:
First, set up the equation as follows: x + (x + 1) + (x + 2) + (x + 3) = ??
Plug in the number you're searching for on the right-hand side of the equation: x + (x + 1) + (x + 2) + (x + 3) = 54.
Now, add like numbers and variables together, to get a sum of 4x + 6 = 54.
The next step to finding 'x' is to subtract the 6 on both sides, leaving you with 4x = 48.
Divide that out, and you get x = 12. Plug that number in the equation above, and you should get 12 + (13) + (14) + (15) = 54.
