Problem Solving (PS) | Re: If x = -1 and if n is the sum of the first 404 prime numbers

If I take the approach that 2 + (3+5+7+11...). The numbers inside the parenthesis are all odd numbers. So won't their sum also be even? and 2 + even = even

Using that I get the answer as 0.

Can someone help where I am going wrong?
