Answer 1

Before jumping in with suggestions, I'd like to know how you've done this type of problem in the past. Have you used summation formulas involving SIGMA?

\[\sum_{2}^{10}(-2n - 3)?\] If y ou know how to use Equation Editor, or are willing to learn how, please use it; the results are so much clearer and easier to read.
