To solve the problem of finding the set of missing pages in the newspaper when page number 17 is missing, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Newspaper:**
A newspaper is made up of sheets, and each sheet has 4 pages (2 on the front and 2 on the back). Since there are 6 sheets, the total number of pages is 6 sheets × 4 pages/sheet = 24 pages.

2. **Visualize the Page Arrangement:**
The pages are arranged as follows:
- Sheet 1: Pages 1, 2, 23, 24
- Sheet 2: Pages 3, 4, 21, 22
- Sheet 3: Pages 5, 6, 19, 20
- Sheet 4: Pages 7, 8, 17, 18
- Sheet 5: Pages 9, 10, 15, 16
- Sheet 6: Pages 11, 12, 13, 14

3. **Identify the Missing Page:**
According to the question, page number 17 is missing.

4. **Determine the Pages on the Same Sheet:**
Since page 17 is on Sheet 4, we need to find all pages on that sheet:
- The pages on Sheet 4 are: 7, 8, 17, and 18.

5. **List the Missing Pages:**
Therefore, if page 17 is missing, the missing pages are:
- 7, 8, 17, and 18.

6. **Conclude the Answer:**
The set of missing pages in the newspaper is {7, 8, 17, 18}.
