You already know 626 ÷ 4 = 156.5.
= 156 (remainder 2)
So 626 = (156 x 4) + 2
Since the pattern 4,0,1,2 repeats,
You should be able to find out what is the 626th number.
627 = 626 + 1 = (156 x 4) + 3
You should be able to find out the 625th and 627th number.
Now, 4 + 0 + 1 + 2 = 7.
Knowing the number of (4,0,1,2) groups,
and knowing the 625th, 626th and 627th number, you should be able to find the sum.
