The integers are -7 and -5.
-2 and 5
5 and -3
-3, 5
The integers are 4 and 9, so the equation would be 16+81=? and 16+81=97
5 + (-3) = 2 5 - (-3) = 8 The two numbers are therefore 5 and -3.
The formula to sum a series of numbers is: sum = 1/2 x number_of_numbers x (first_number + last_number) So to sum the integers 5 to 500: From 5 to 500 there are 500 - 5 + 1 = 496 integers, so sum = 1/2 x 496 x (5 + 500) = 125240
It need not be. 2 and 3 are consecutive integers and their sum is 5, not 31.
Let's denote the two integers as x and y. We know that x + y = -9 and x - y = 5. By solving these two equations simultaneously, we can find that the two integers are -7 and -2. This is because -7 + (-2) = -9 and -7 - (-2) = 5.

-15 and 5.
The answer is -5.
