Sure! Let's break down the process of finding the average of the given numbers (6, 8, 10, 12, 14, 16, and 18) step by step.
1. List the numbers: 6, 8, 10, 12, 14, 16, 18.
2. Calculate the sum of the numbers:
- Add the numbers together:
[tex]\[
6 + 8 + 10 + 12 + 14 + 16 + 18 = 84
\][/tex]
3. Count the numbers:
- There are 7 numbers in the list.
4. Calculate the average:
- The average is calculated by dividing the sum of the numbers by the count of numbers:
[tex]\[
\text{Average} = \frac{\text{Sum}}{\text{Count}} = \frac{84}{7} = 12
\][/tex]
Therefore, the average of the given numbers is 12.
So, the correct answer is:
A. 12
