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?
Answer
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).
