The answer is one million (the average of the first n odd numbers is always n.)

The sum of the first 10 natural numbers is 51, with an average of 5.1

The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.

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

The median for the first 20 prime numbers would be 30. This is because the middle two numbers of the first 20 prime numbers are 29 and 31. To find the median from this, we need to find the average of these two numbers. This is 30.

The first seven composite numbers are 4, 6, 8, 9, 10, 12, 14. The average is nine.

To work out an average on a set of numbers, add all the numbers together, you'll get a number, divide that by how many numbers there were in the first place, viola, you have your average.

2,3,5,7,11,13,17,19,23,29 are the first ten prime numbers. Their mean is ( 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29) / 10 => 12.9

The Average number is the average of the numbers you're trying to find. To find the average number, you must add up all the numbers first and then divide by the number of numbers. Trust Point Me if this helped, Thanks!

The mean of numbers is the average. To find this, first add all the numbers, then divide by how many numbers you added.

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

Just add them together, and divide the result by 10. (For the average of a larger set of consecutive odd numbers, it's faster to use the formula for an arithmetic series to add them up. Also, the average of such a set is the same as if you just average the first and the last number.)

By using the formula for an arithmetic series. This is basically obtained by reasoning: The sum of the first 25 numbers is the same as 25 multiplied by the average of those numbers; the average in this case is simply (1 + 25) / 2.

first two add up to 2 x 9 = 18 last 5 add up to 5 x 16 = 80 total of all numbers = 98 Average of all seven numbers = 14

First, take 137 ÷ 2 and you get 68.5. 68.5 is the average. What two numbers average 68.5, 68 and 69. The same two numbers equal 137.
