------
1st:: x-2
2nd:: x-1
3rd:: x
4th:: x+1
--------------------
Equation:
3x-3 = (x+1)+20
---------------------
2x = 24
x = 12
-----
1st:: x-2 = 10
2nd:: 11
3rd:: 12
4th:: 13

Determine four consecutive integers such that the sum of the first three integers is 20 more than the fourth integer
Let the smallest integer be S
Then the others are: S + 1, S + 2, and S + 3
Equation needed: S + S + 1 + S + 2 = S + 3 + 20
Solve for S, the smallest
Count by 1s after to get the other 3, or add to the preceding to get the next larger
