The first five even natural numbers are 2, 4, 6, 8, and 10. To find the mean of these numbers, follow these steps:
- First, add the numbers together: 2 + 4 + 6 + 8 + 10 = 30.
- Next, count how many numbers there are. In this case, there are 5 numbers.
- Finally, divide the total sum by the number of values: 30 ÷ 5 = 6.
Therefore, the mean of the first five even natural numbers is 6.
