To find the mean of a set of numbers, you add all the numbers together and then divide by the total count of numbers.

1. Add the numbers:
\[
5 + 7 + 9 + 11 + 18 = 50
\]

2. Count the numbers in the set:
There are 5 numbers.

3. Divide the sum by the count:
\[
\text{Mean} = \frac{50}{5} = 10
\]

Therefore, the mean of the set of numbers is \( 10 \).
