What is the average of the numbers 2, 4, 6, and 10?

To find the average of a set of numbers, you first add all of the numbers together and then divide the sum by the count of the numbers.

In this case, the numbers are 2, 4, 6, and 10.

First, we add these numbers:

2 + 4 + 6 + 10 = 22

Next, we count how many numbers there are:

There are 4 numbers.

Now, we divide the sum by the number of numbers to find the average:

22 ÷ 4 = 5.5

Thus, the average of the numbers 2, 4, 6, and 10 is 5.5. This calculation confirms that option B is correct, as it accurately reflects the average after performing the necessary arithmetic operations.
