What number completes this sequence?

What number completes this sequence please?

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

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

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

• Isn't there a lot of possibilities then? Maybe I didn't understand, what allows us to choose one among the others? – Untitpoi Jul 9 '18 at 14:46
• I don't quite understand what you are asking. Can you explain your question more? – Emre Ünsal Jul 9 '18 at 14:50
• What if I use 73 or 233456778? It would also make a pattern. – Untitpoi Jul 9 '18 at 14:54
• 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. – 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

• I don't think 95 is a multiple of 7. – Laconic Droid Jun 10 '18 at 16:03
• 102 isn't a multiple of 7 either... could you explain your reasoning a bit further, please? – puzzledPig Jun 10 '18 at 16:27
• 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. – F1Krazy Jun 10 '18 at 16:31
• It has nothing to do with multiples. – Vincent Mia Edie Verheyen Jun 10 '18 at 23:24
