The answer is B, because x-7/7-x will equal the negative version of the number on each end, which divided to -1.

What is the sum of the terms of the series (−1) + (−2) + (−3) + . . . + (−10)?

Murrr4er [49]

You can solve this problem by using the Gauss method. The Gauss method is a method where you can add the first and last numbers together, and then multiply by how many times that appears. Here, the sum of the first and last number is -11. In this sequence, it would appear ten times (since there are ten terms and the terms are used twice in every eleven). -11 * 5 is -55, so that means the answer to this question is -55.
