# Sequence seen on the street

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?

• 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 Oct 20, 2016 at 13:45
• @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? Oct 20, 2016 at 13:59
• Nope. that's why I think this is a trivial question and I wrote my answer as a comment. Oct 20, 2016 at 14:00
• 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?

• @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). Oct 20, 2016 at 15:02
