You can put this solution on YOUR website! sum of four consecutive integers is 686, then what is the sum of four previous consecutive integers ?
------
n + n+1 + n+2 + n+3 = 686
n-1 + n-2 + n-3 + n-4 = 686 - 16 = 670

:
Find the first of the 4 integers that add up to 686
n+(n+1)+(n+2)+(n+3) = 686
4n + 6 = 686
4n = 680
n = 680/4
n = 170
then the previous four:
169+168+167+166 = 670
