You can answer this by using the following formula:
$\sum^n_{i=1}i=\dfrac{n(n+1)}{2}$
The proof of which can be found here. If we rephrase your question in mathematical terms, using this sum notation, you are asking:
$\sum^{1000}_{i=100}i=?$
This is equal to
$\sum^{1000}_{i=1}i-\sum^{99}_{i=1}i$
So use the formula above with these values to get the answer.
