Use the formula for the sum of the n integers and subtract them.
for the integers up to 149
Then do the same for 366
Then subtract the two results.

What's your answer? I just gave the formula for the sum of the first n integers.
Well-known if you're studying sequences.

That is why we sum from 1 to 149 and then 1 to 366 and subtract.
67161-11175=55986

The nth partial sum is given by
Where n=125 and
