We are tasked with finding how many people have read exactly two consecutive issues of Playboy magazine (out of July, August, and September) based on the given survey data.

1. July and August
2. August and September
3. July and September (Note that these two months are not consecutive, but the problem includes both pairs.)

We are interested in those who read exactly two consecutive issues, so we will only count the pairs without considering those who read all three months.

Step 2: Find the total number of people who read only August and September

Step 3: Read exactly two consecutive
