The answer is -5.
-4 and -5
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
5 & 10
-4 and -1
The integers are -7 and -5.
It need not be. 2 and 3 are consecutive integers and their sum is 5, not 31.
To find the sum of two integers with different signs, you simply combine them, and give the result the sign of the larger integer. For example, you have two integers: -9 and +5. You combine them, that is the +5 cancels out 5 of the -9, leaving -4.
-3,-4,-5
-15
The integers are odd and they are 3, 5, 7 and 9.
The integers are 5, 6, 7 and 8.
