I was walking on the street when I saw the following numbers:

$0, 7, 2, 3, 9$

The sequence continued a bit further then looped back. However, it was not the sequence I was expecting, so it took me a moment to figure out what was going on.

Where were these numbers? And what was going on?

    $\begingroup$ You are on an infinite length street and someone wrote on lamp posts the decimals of $\frac{\pi}{17}$ but for some reason you are running around in circles $\endgroup$

  • $\begingroup$ @Marius I have never expected anything else than the decimals of π/17 any time I walked around in circles on infinite length streets. Have you? $\endgroup$

    $\begingroup$ Hm, I have a suspicion that the answer to this might be related to the answer to my as-yet unsolved puzzle at puzzling.stackexchange.com/questions/43293/…. I see a pattern that fits, but am loath to reveal it as it would give away the solution to mine. Does the solution to my puzzle look like it might be similar to the solution to yours? $\endgroup$

    $\begingroup$ @lois6b That's what the puzzle asks! Although, to be fair, the question may be a bit vague so: the numbers are on something (whose functionality is provided by said numbers). That something may be on a wall, a post or somewhere else (but probably not on the floor). $\endgroup$

It was on a

seven-segment display counting upwards (eg a clock), but the top segment was stuck on, so 1 is the same as 7, and 4 looks similar to a 9 (even though the bottom segment would normally be on as well in a 9).

  • $\begingroup$ That's correct! $\endgroup$
