To find the mean of a set of numbers, you add all the numbers together and then divide by the total count of the numbers. In this case, the numbers are 2, 4, 6, and 8.

First, let's add them together:

2 + 4 + 6 + 8 = 20

Next, we count the total numbers, which is 4.

Now, we divide the total sum by the number of values:

20 ÷ 4 = 5

This means the mean of the numbers 2, 4, 6, and 8 is 5. Therefore, the correct answer is the one that represents this value. Understanding the procedure for calculating the mean is crucial, as it helps in situations where you may need to analyze data sets and find average values.
