To find the sum of a set of numbers, you can use this formula: ∑ = (x)(x+1)/2 That is..... The sum = (The number of samples)(The number of samples + 1)/2 Example: What is the sum of all numbers between 500 and 1000? Assuming that we do not include 500 or 1000 in our answer, we have 498 numbers to add up. Let's put that into the formula.... ∑ = (498)(498+1)/2 ∑ = (498)(499)/2 ∑ = (248,502)/2 ∑ = 124,251 The Answer is 124,251

How do you find the missing number in a set of numbers where the average is given?
The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
If the sum of six consecutive even numbers of set A is 402. What is the sum of another set B of four consecutive numbers whose lowest number of set A?
It is 260.
Find two consecutive even integers whose sum is -96?
There is no set of two consecutive even numbers that total -96. There is only a set of odds. The numbers are -49 and -47.
What is the sum of a set of numbers divided by the number of elements?
the mean or average of the set
