364. Once I decided to take a ride on a chairlift. At some point, I noticed that the chair coming towards me had the number 95, and the next one had the number 0, followed by 1, 2, and so on. I looked at the number on my chair; it turned out to be 66. Have I passed the halfway point? At which chair will I pass the halfway point?
$\triangle$ Total number of chairs is 96, and half the journey consists of 48 chairs. I will be in the middle of the cable car when the number of chairs ahead and behind me is the same. For this to happen, the number of the oncoming chair must be equal to $66-48=18$. Since the encounter with chair number 18 is ahead of me, I have not yet traveled half the journey.

Answer: not traveled; 18
