The middle seat is situated at the middle position.

From the question, if the price for the aisle and middle seat are between P1 and P2, passengers will demand for the aisle seat first which will lead to a shortage in aisle seat. Only then will the middle seat be demanded for until it reaches equilibrium with the aisle set.
