Find the mean of the first five even natural number?


  • Natural numbers are part of the number system that comprises all the positive integers from 1 to infinity and are often used for the purpose of counting.
  • Zero not include in natural numbers. In reality, 1,2,3,4,5,6,7,8,9…. are known as counting numbers.
  • Natural numbers are real numbers, which only contain positive integers, i.e. 1, 2, 3, 4,5,6, ………. With zero, fractions, decimals, and negative numbers excluded.

The first five even natural numbers are 2, 4, 6, 8, 10…

The mean of the numbers can be calculated using the formula

Mean = Sum of the observations/ Number of observations

Sum of the observations is

⇒ 2 + 4 + 6 + 8 + 10


A number of observations are 5.

Substitute the values in the above equation

Mean = 30/5

Mean = 6

∴ The mean of the first five even natural numbers is 6.
