Alright, so number sequence puzzles have been falling off a little bit. Puzzlers have been at a loss at how to combat this for some time, and I wanted to try to give it some thought. Right away, I thought of sequences related to pi and what-not. In trying to come up with something, however, everything was too obvious or too hard. Later, I tried e (Euler's constant), but with the same results. For all my efforts, I couldn't come up with anything. On the whole, I was stumped. Once more, I tried to come up with something brilliant and clever, and this time I succeeded! Laws of nature sure make great puzzles (I dare not say more). So, enjoy this spectacular number puzzle!

234, 98123, 53491, 1239, 0984132, 2, -932, 542701, 90231, 45, 87610, 43619082, 3149, ???

What is the pattern?

Well, at least part of the pattern is

that the first letters of the sentences spell APRIL FOOLS.


those sentences look a bit more constrained than they need to be just for that, so it's possible that I've missed something else. (The numbers, though, look a lot like the result of a keyboard-mash -- lots of short increasing and decreasing sequences, e.g. -- and I bet there's nothing useful in them regardless.)

  • $\begingroup$ Yep, this one is super-simple. Just a little goofiness to match the unicorns today :) Will retag my question to reflect its true nature. $\endgroup$ – Brandon_J Apr 1 '19 at 2:25
  • $\begingroup$ I wondered whether I should refrain from solving it out loud... $\endgroup$ – Gareth McCaughan Apr 1 '19 at 2:33
  • $\begingroup$ Ah, fine as is. Probably would have accumulated some close votes from annoyed mathematicians if you hadn't. Also, I only spent about 2 mins on the puzzle itself, so it's not like you're messing up well-laid plans or anything. $\endgroup$ – Brandon_J Apr 1 '19 at 2:37
  • $\begingroup$ Pro tip: If you're looking to fool people with random fake numbers, you might want to avoid certain things such as unnecessary leading 0's, and sequences of adjacent digits which just scream "button mashing"... $\endgroup$ – Darrel Hoffman Apr 1 '19 at 12:47

    $\begingroup$ Indeed. But I don't think Brandon was trying very hard to fool people :-). $\endgroup$ – Gareth McCaughan Apr 1 '19 at 14:19
