Since the maximum number of people is 13... hmmm...

It doesn't really matter which 2 stools are chosen. I mean, say you choose 1 and 25. The first person sits down at 1. The next person decides to sit at 4. Then the next at 7. That doesn't work out, no one said they have to sit with one stool inbetween.

The Antisocial Club meets every few weeks at Jim's Bar. Since they are so antisocial, however, everyone always sits as far as possible from the other members and no one ever sits right next to another member. Because of this, the 25-stool bar is almost always less than half full and unfortunately for Jim the members that don't sit at the bar don't order anything. Jim, however, is pretty smart and makes up a new rule: The first person to sit at the bar has to sit at one of two particular stools. If this happens, then the maximum number of members will sit at the bar. Which stools must be chosen? Assume the stools are numbered 1 to 25 and are arranged in a straight line.
