Use set-builder notation to write the following set.
\[
\{7,14,21\}
\]
$\{x \mid x$ is a multiple of 6 and $6< x< 22\}$
$\{x \mid x$ is a multiple of 6 and $7< x< 21\}$
$\{x \mid x$ is a multiple of 7 and $7< x< 21\}$
Onone of these
$\{x \mid x$ is a multiple of 7 and $6< x< 22\}$
Answer
Final Answer: The set can be written in set-builder notation as \(\boxed{\{x \mid x \text{ is a multiple of 7 and } 6<x<22\}}\).
Step 1 ：Use set-builder notation to write the following set: \(\{7,14,21\}\).
Step 2 ：The set contains the numbers 7, 14, and 21. These numbers are all multiples of 7.
Step 3 ：Therefore, the set can be described as the set of all x such that x is a multiple of 7 and x is between 6 and 22.
Step 4 ：Final Answer: The set can be written in set-builder notation as \(\boxed{\{x \mid x \text{ is a multiple of 7 and } 6
