To solve this, try to understand what I'm about to do.
The first two numbers are 1 and 3
the last two numbers are 1997 and 1999
1 + 1999 = 2000
3 + 1997 = 2000
etc.
Therefore, the numbers can be paired in groups of two. If you did this to every number, you would see that there are 500 groups.
So, there are 500 groups that sum to 2000
so multiply the two and you will get 1,000,000
