Solution Steps

To convert the given roster notation to set builder notation, we need to identify the pattern in the set. The set contains even numbers starting from 2 and ending at 26. We can express this as a set of all even integers between 2 and 26 inclusive.

Step 1: Identify the Set

The given roster notation is \(\{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26\}\). This set consists of even integers starting from 2 and ending at 26.

Step 2: Express in Set Builder Notation

To express this set in set builder notation, we can define it as: \[ \{ x \in \mathbb{Z} \mid 2 \leq x \leq 26 \text{ and } x \text{ is even} \} \] This means \(x\) is an integer between 2 and 26, inclusive, and \(x\) must be even.

Step 3: Verify the Set

The set builder notation correctly represents the original set, as it includes all even integers from 2 to 26. The output confirms that the set is: \[ \{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26\} \]

Final Answer

The set in set builder notation is: \[ \boxed{\{ x \in \mathbb{Z} \mid 2 \leq x \leq 26 \text{ and } x \text{ is even} \}} \]
