GAUSS8 2011 Problem 25

Daryl first writes the perfect squares as a sequence

1,4,9,16,25,36,49,64,81,100, \ldots

After the number 1, he then alternates by making two terms negative followed by leaving two terms positive. Daryl’s new sequence is

1,-4,-9,16,25,-36,-49,64,81,-100, \ldots

What is the sum of the first 2011 terms in this new sequence?
