Is the e suppose to be in there? Cause if it is then you would probably have to have a number equaling to it to solve for e. If not then here is how you do it. Just add them together.

Answer:
998,001
Step-by-step explanation:
Sum (S) of n terms in an arithmetic sequence is given by;
= 
(2a + d(n-1)) , where d is the common difference
= 
(2 + 2(999-1)) = 998,001
First number = x
Consecutive number = x+1
"squares differ by 31" means to square both numbers and subtract them:
(x+1)^2 - (x)^2 = 31
x^2+2x+1 - x^2 = 31
2x+1 = 31
2x = 30
x = 15 (first number)
x+1 = 15+1 = 16 (consecutive number)
