Detailed explanation-1: -It’s obtained by simply dividing the sum of all values in a data set by the number of values.

Detailed explanation-2: -Natural numbers begin at 1 and increment to infinity: 1, 2, 3, 4, 5, etc. Therefore, the first ten natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. And the mean of three numbers a, b, c is a + b + c3. Hence, the mean of the first 10 natural numbers is 5.5.
