What does this equal to?

\( \sum 11 n=1 (98-2n)\)

I'm pretty sure that this equation is missing some things.

First of all, a sigma notation must have a range, from n=x to k

This is missing the range, so this problem is undoable.

I can help you if you repost with the missing values.

I know it may seem that way, but this was all that was apart of the question. I don't know why, my teacher set it up this way

If this is what your teacher meant: ∑(98-2n), n=1 to 11, then it sums up to = 946.
