The answer is one million (the average of the first n odd numbers is always n.)
50.5
To find the average of all seven numbers, we can use the formula for the average: (sum of all numbers) / (total number of numbers). Given that the average of the first four numbers is 15, the sum of the first four numbers is 15 * 4 = 60. Similarly, the sum of the last three numbers is 8 * 3 = 24. Therefore, the sum of all seven numbers is 60 + 24 = 84. Finally, the average of all seven numbers is 84 / 7 = 12.
The mean of numbers is the average. To find this, first add all the numbers, then divide by how many numbers you added.
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.
The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.

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.
