      He spends the first 5 minutes explaining the answer is 4, but the question was also worded ambiguously that 3 and 1 can also be correct answers.

      Maybe watch the video, it’s more interesting than you’d think

      How did this video stretch out to 18 mins?
      I remember a mindyourdecisions yt video about this from several years ago that showed it in a couple of minutes and why it is n+1.
      sorry i don’t remember the url though.

        It explains the answer is 4 before the 5 minute mark.

        Part of the reason is because it goes into the story of the SAT being wrong and a student being the one to catch it, which I found interesting.

        After that it mathematically proves it several different ways and then shows how it relates to some real problems in astronomy.
