A math question on progression

A boy starts adding consecutive natural numbers starting from 1. After sometime he reaches a total of 1000 when he realizes he has double counted a number. What is the number he has double counted??

As far as I can figure, he has double counted the number ten (10).

I wish I had a brilliant mathematical answer, but it's been far too long since I have taken any math! I just did this via the brute, clumsy way of adding numbers. When I reached a total of 990, I knew the only way to reach exactly 1000 was with a 10.
