Jenny makes a list of all the integers from a to b, including a and b. Find a formula in terms of a and b for the average of Jenny's numbers.

 

What is the answer?

 

Thnx,

Add up all the numbers from a to b and divide the total by the number of terms:

Example: 1 + 2 + 3 + 4 + 5 = 15. Then you would divide this by 5, which is the number of terms:

15 /5 = 3 - This would be the average of Jenny's list. So, the formula would look like this:

[a + ...... + ...... b] / n = the average, where n = number of terms.
