Answer 1

Answer: (A) 2

The sum of the integers from -2015 to 2017 = 2

Explanation:

The sum of integers a and b is represented as a+b.

The sum of the integers from -2015 to 2017 = -2015+2017

Since -a+b=b-a

Thus, The sum of the integers from -2015 to 2017 = 2017-2015 = 2

i.e. The sum of the integers from -2015 to 2017 = 2

Thus , the correct option is (A).
