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.
