First 3 composite numbers: 4+6+8 = 18 and 18/3 = 6 which is the average number

The average of the first ten prime numbers is 12.9.
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.
36 is composite because it can be evenly divided by numbers other than 1 and itself. Specifically, it can be divided by 2, 3, 4, 6, 9, 12, 18, and 36.
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.
3 x 5 x 5 = 75

18 is composite. 18 = 2 * 3 * 3 = 2 * 32
average of first five prime numbers = 5.6 first five prime numbers = 2, 3, 5, 7, 11average = sum of first prime numbers/5= (2 + 3 + 5 + 7 + 11)/5= 28/5= 5.6
The average of the first ten prime numbers is 12.9.
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.

To find the average of a number, first you add all the numbers that you want to average. Then you need to divide the sum of the numbers by the number of numbers there were. So if a set of numbers is 3, 5, 7, 1, 4, 7, 8 The equation would be 3+5+7+1+4+7+8=35/7(for the 7 numbers)=5
Yes. For example, the average of the numbers 1, 2, and 3 is 2. 1+2+3=6 6/3=2
36 is composite because it can be evenly divided by numbers other than 1 and itself. Specifically, it can be divided by 2, 3, 4, 6, 9, 12, 18, and 36.
First, add all the numbers. Next, divide the sum by how many numbers there were. Example: 34 + 23 12 ----------- 69 69 divide by 3 is ... 23: That is your average.
