You can put this solution on YOUR website! If the first integer is x, then the second must be x + 1, the third x + 2, and the fourth x + 3. Their sum must then be . This sum is one more than the third. The third consecutive integer is x + 2, so one more than that is x + 3. Therefore we can write:
Removing the parentheses and collecting terms gets us to:
Add -x to both sides and add -6 to both sides:
Divide by 3
Therefore the integers are -1, 0, 1, and 2.
Check: -1 + 0 + 1 + 2 = 2, so the sum of the integers is 2.
The third is 1, and one more than that is 2. Answer checks.
