Beside this, what is the mean of first 10 natural numbers?

The first 10 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. Mean = Sum of Observations/Total No of Observations. Mean = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 ÷ 10. Mean = 55/10. Mean = 5.5.

Also, how do you find the mean of first n natural numbers?

1. Sum of first n natural numbers = n(n+1)/2.
2. To find the mean, We divide the sum by the total number of entitities, which is n in our case.
3. So, Mean = {n(n+1)/2}/n.
4. So, Mean = (n+1)/2.

Moreover, what is the mean of first n odd natural numbers?

The mean of first n odd natural number is. We know that mean or average of observations, is the sum of the values of all the observations divided by the total number of observations.

What is the odd natural number?

Odd number. An odd number is an integer when divided by two, either leaves a remainder or the result is a fraction. One is the first odd positive number but it does not leave a remainder 1. Some examples of odd numbers are 1, 3, 5, 7, 9, and 11.
