The average is 2 - Adding all the numbers together gives a total of 42. There are 21 numbers in the range - therefore the average is 2.
It is 1.
The arithmetic mean is 36.

it is 33; you can add all up and divide by 17, or simply add first and last and divide by 2
The sum of the integers 1 to 99 is 4950. An easy way to figure this out is using the equation N*(N+1)/2 where N is the largest number in the set.
It is 1.
The average is zero.
To find the average of integers, add them all together then divide the total by the number of integers.
The sum of all integers from 1 to 20 inclusive is 210.
The average is -3
Counting all integers from 1 to 238 inclusive, there are 606 digits between these two numbers.
1 is a common factor for all integers.
The arithmetic mean is 36.

810. All of the integers from -30 to30 cancel each other out by adding a negative to a positive. Then all you need to do is add the integers from 31 to 50. (31 + 32 + ....+50)
it is 33; you can add all up and divide by 17, or simply add first and last and divide by 2
The sum of the integers 1 to 99 is 4950. An easy way to figure this out is using the equation N*(N+1)/2 where N is the largest number in the set.
