# The Ultimate Number Sequence Puzzle

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?

• Happy April Fool's Day, everyone! Just thought I'd spread a little silliness. Commented Apr 1, 2019 at 2:29

Well, at least part of the pattern is

that the first letters of the sentences spell APRIL FOOLS.

But

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.)

• Yep, this one is super-simple. Just a little goofiness to match the unicorns today :) Will retag my question to reflect its true nature. Commented Apr 1, 2019 at 2:25
• I wondered whether I should refrain from solving it out loud... Commented Apr 1, 2019 at 2:33
• 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. Commented Apr 1, 2019 at 2:37
• 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"... Commented Apr 1, 2019 at 12:47
• Indeed. But I don't think Brandon was trying very hard to fool people :-). Commented Apr 1, 2019 at 14:19
