It’s the Friday Puzzle!

42

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.  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.  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.

    Solved ^-^
    Took me about 10 seconds

    <33

  2. Roland says:

    20 seconds🙂

  3. Mike Hitchcock says:

    Brian not in gear this morning – need more coffee…5 minutes before it clicked.

  4. Anonymous says:

    Answer “struck” on third reading.

  5. Took me a few minutes… I’m pretty sure I’ve seen this one before, because once I “got it”, it felt awfully familiar.

  6. Charles Sullivan says:

    You many geniuses here. No clue yet.

  7. Jenny D says:

    5-10 seconds, I think. I may have seen it before, though.

  8. Criticalbounce says:

    About a minute. Not seen it before but think I see the process. Monday will tell…

  9. Rob says:

    Tempting to slip a 13 in there to gum up the works ;

  10. Tom Pedersen says:

    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…

  11. Michael Sternberg says:

    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.

  12. Laurent says:

    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…

  13. KJ says:

    Took me at least half an hour!

  14. Damocles says:

    Sure I’ve seen this before somewhere, it certainly rings a bell.

  15. Hugh Jarse says:

    Got it in 1.7356875235676347 seconds.

  16. Adam says:

    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.

  17. Mad Kev says:

    Took me about half an hour before it struck me.

  18. Lazy T says:

    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,…..?

  19. Mal says:

    Got this one after 5 mins or so and a cup of coffee!

  20. Rob says:

    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’. ;^)

  21. Ian says:

    Took half an hour, though I was expecting it to be a quarter!

  22. Jarl says:

    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.

  23. Got it but not immediately. Took me about 2 minutes. I’m impressed by those who got it in 10 seconds.

  24. Jacqualine says:

    Got it in about 30 seconds; goggled it to be sure, and although correct, did not have that same reasoning!

  25. UXO says:

    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.)

  26. Tom Green says:

    Not seen it before. Got an answer in about 3 mins. I’m sure its right Though keen to check on Monday.

  27. NoAstronomer says:

    Took me all day, well most of the day, but I did eventually figure it out.

  28. Niels says:

    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🙂

  29. spiderabc1 says:

    It was on reading it the third time I clicked and the lightbulb flashed above my head.

  30. JayCee says:

    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.

  31. Match says:

    This one is too well known

  32. dharmaruci says:

    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
