    $\begingroup$ I'm betting that there's more to this than meets the eye; @Chowzen do you, in good faith, think it should be reopened? (I know you said "Vote to close!" but guess that's part of some joke.) $\endgroup$ – Gareth McCaughan Feb 23 at 13:30

    $\begingroup$ You can probably fix this by adding some story. Since I gather there is a physics connection, have a student and teacher conversing. Present the first part of the sequence and have the student think it's just the positive integers, have them be wrong about 8, keep going, and then have the student realize after 15 "oh, I get it!" - this flavour text will ideally include a few hidden puns that confirm everything for those who know what you're referring to. Then it's a good puzzle. $\endgroup$ – Kate Gregory Feb 23 at 15:17

The sequence continues

with eight, and then stops.

because they are

playing eight-ball, which has fifteen balls, but you're supposed to sink eight last. I guess the game went like this: the first player sank the first seven (solids), but missed the eight. Then the second player got the next seven (stripes). And then got the eight to win. Or, the second player also missed the eight, and then the first player got the eight to win on the next attempt.

    $\begingroup$ Not really sure where the physics tag comes in, unless it's in the rot13(zbirzrag bs gur onyyf). $\endgroup$ – ZanyG Feb 25 at 6:46
