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.

Step-by-step explanation:
hello :
×-5y=-15
5y = x+15
y = (1/5)x+3 for x= - 5 y = (1/5)(-5) +3 so : y = 2
