Times of a hidden order

The goal is to find the 6th time of a set of six different times on a clock. In order for this set of times to be complete, what time must replace the question mark? As usual, explain why.

• Just want to say, so to not waste your time, notice the lack of "sequence"-tag. Hence why I used "set" instead. The set you see is simply arranged in "time of the day"-order, starting with the earliest to latest. Also, try to make sense of the title. Commented Jul 1 at 11:31

The times on the clocks are

131, 232, 235, 711, 719

This set may be

rearranged as: 235 711 131 719 232
which splits into 2, 3, 5, 7, 11, 13, 17, 19 23, 2

So a 6th time would be

931 to continue the sequence of primes

The title may clue how the

times are rearranged. I see ORDER, rearranged alphabetically to DEORR to clue this?

• Correct, well done! The title was just clueing "hidden order" (order of p's). These are all 6 times possible in order since the next would be 3:74 Commented Jul 1 at 14:35
