If the only thing you're told is the average, there's no way to figure out what the individual numbers are. There are an infinite supply of groups of numbers that all have the same average. If you need to find the individual numbers, you need a lot more information besides just their average.
To get the simple average of a series of numbers, you add the numbers up and divide by however many numbers there were. For example, the average of 2, 3 and 4 is the sum of the numbers (which adds up to 9) divided by 3 (because there are three numbers). So the average is 9/3 = 3.
It average of 2 numbers is 9 then take 9 away from 12, so average of 3 numbers is now 9, with 3 'left over.' The 3 which is 'left over' divides among the three numbers by adding 1 to each of them, raising the new average to 10.
First 3 composite numbers: 4+6+8 = 18 and 18/3 = 6 which is the average number
Add all the numbers together. Then divide by how many numbers there were originally. That is the average.

If you have a list of numbers for which you want to find the average, Example: 3, 4, and 5 The first thing that you need to do is figure out how many numbers there are in the list: Example: 3 Then you need to find the sum of the numbers in the list: Example: 3 + 4 + 5 = 12 Then you divide the sum by the number of numbers in the list: Example: 12 / 3 = 4 And the result is the average of the numbers.
To figure the variance on a group of numbers, you must first figure out the mean, which is the average of the set. Then, substract the mean from each number in the set. Square the result of those substractions, and then average the squares. You will then have the variance.

The average of 3, 3.5, and 6 is 4.17. Add the three numbers together and divide by 3 to find the average.
2
Yes. For example, the average of the numbers 1, 2, and 3 is 2. 1+2+3=6 6/3=2
Prime squares
Add them together. Divide that total by 10.
Add the 3 numbers together and divide that answer by 3. Example: The average of 2, 4, and 9. Average = (2+4+9)/3 = 15/3 =5.
It average of 2 numbers is 9 then take 9 away from 12, so average of 3 numbers is now 9, with 3 'left over.' The 3 which is 'left over' divides among the three numbers by adding 1 to each of them, raising the new average to 10.
