A nice quick one this week…..What are the next four numbers in this sequence…..

12, 1, 1, 1, 2, 1, 3, ……..?

As ever, please do NOT post your answers, but do say if you think you have solved the puzzle and how long it took.Β  Solution on Monday.

Oh, and if you have a few minutes spare, it would be great if you could help out with the quick survey being conducted by psychologist and friend Rob Jenkins.Β  Details here.

I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for the Kindle (UK here and USA here) and on the iBookstore (UK here in the USA here). You can try 101 of the puzzles for free here.

  1. Haven’t this puzzle been here before? I got the puzzle as soon as I read the second number, and I was sure it was on this blog I saw it. However, when I searched for the answer + wiseman, I couldn’t find it. Found a few similar puzzles here, though.

    weird…

  2. About a minute (ahem, cough).

    After that, googling told me the same answer, but for another reason. Folks will chime in with different ways. Monday is going to be interesting.

  3. 10 seconds at first, then I re-read the sequence.
    The puzzle’s sequence is:
    12, 1, 1, 1, 2, 1, 3, …
    Note that it is NOT:
    12, 1, 1, 1, 2, 3, 1, …
    as in another puzzle…

  4. had to google it. Glad I did, would have never gotten it. For thos that struggle there are some subtle hints in the above comments.

  5. It took me about one ‘interval’ to recognise the pattern, here’s another wind up….what are the next four numbers in this sequence? 8, 8, 8, 8, 8, 8, 8, 8, 8, 8,…..?

  6. I got it in about 30 seconds, which is precisely the time it took me to read the ‘subtle’ clues in the comments.
    By subtle, I obviously mean ‘glaringly obvious giveaways’. ;^)

  7. I found the correct pattern without knowing why it was correct in like 15s. Had to google the reason for it. Now it seems amazing that I did not get the last part.

  8. Instantly. But I’ve got a piece of equipment which characterizes this sequence, and came up with a similar brainteaser on my own for my kids based upon it. (Let’s just say it has to do with the maximum number of 1’s before one can be certain of something.)

  9. Got it almost immediately (heard it before), but don’t like some of the puzzles lately. They aren’t really logical, but require some knowledge that isn’t available to everyone, or might be different.
    My dad taught me the principle behind this puzzle 25+ years ago, but I doubt a lot of the younger kids today know this one.
    Sigh, I must be feeling old this morning πŸ™‚

  10. This time I even recognised the pattern before reading the question
    so recognition was less than a second, verification took then around 7 secs and writing this statement took the longest.

  11. i do not believe this one is capable of solution. please do not waste your time over the weekend, when me wiseman returns to the office he will correct the sequence to something solvable
