What number completes this sequence please?

1, 2, 68, 14, 21, 89, 49, 56, 37, 95

$\endgroup$
  • $\begingroup$ Does the fact that 89 is 68 turned upside-down have anything to do with it? $\endgroup$ – PotatoLatte Jun 10 '18 at 13:35
  • $\begingroup$ @ZaniXu Well spotted, but no. $\endgroup$ – Vincent Mia Edie Verheyen Jun 10 '18 at 13:52
  • $\begingroup$ does the order of the numbers in the sequence you wrote matter? $\endgroup$ – Emre Ünsal Jul 9 '18 at 14:04

I think the answer is

5

because

it almost creates a pattern when we take the amount of the numbers
(ex: 1 used 3 times, 2 used 2 times etc.)
1-2-3-4-5-6-7-8-9 (numbers)
3-2-1-2-2-2-1-2-3 (amount of numbers in the sequence)

so

if we add 5 to the sequence the amount of numbers from 1 to 9 is going to be a pattern itself like 3-2-1-2-3-2-1-2-3

  • $\begingroup$ Isn't there a lot of possibilities then? Maybe I didn't understand, what allows us to choose one among the others? $\endgroup$ – Untitpoi Jul 9 '18 at 14:46
  • $\begingroup$ I don't quite understand what you are asking. Can you explain your question more? $\endgroup$ – Emre Ünsal Jul 9 '18 at 14:50

    $\begingroup$ What if I use 73 or 233456778? It would also make a pattern. $\endgroup$ – Untitpoi Jul 9 '18 at 14:54

    $\begingroup$ If this is the right answer, then I would not consider the numbers in the question to be a sequence. Their order does not matter. The way the digits are composed into larger numbers does not matter. Those are essentially random aspects added to a collection of digits to make it look like a sequence even though it really isn't one. If the question had presented a (multi)set of digits and asked which one was missing, it would be more logical, but presenting it as a sequence is misleading and in my opinion then makes the answer rather unsatisfying. $\endgroup$ – Jaap Scherphuis Jul 9 '18 at 15:36

Does the fact that

14, 21, 49, 56, and 95 are all multiples of 7

have to do with it? My guess would be

102

    $\begingroup$ I don't think 95 is a multiple of 7. $\endgroup$ – Laconic Droid Jun 10 '18 at 16:03

    $\begingroup$ 102 isn't a multiple of 7 either... could you explain your reasoning a bit further, please? $\endgroup$ – puzzledPig Jun 10 '18 at 16:27
  • $\begingroup$ Also, answers need to be hidden in spoiler tags. In the unlikely event that this is the correct answer, you're currently spoiling it for anyone who wants to have a go at the puzzle themselves. $\endgroup$ – F1Krazy Jun 10 '18 at 16:31
  • $\begingroup$ It has nothing to do with multiples. $\endgroup$ – Vincent Mia Edie Verheyen Jun 10 '18 at 23:24
