Question 1102282: is there a pattern that repeats or a way to predict next number in this string: 2,3,5,9,2,6,12,2,12,10,2,9,1,11,4,5,12,11,8,8,5,8,8,12,9,7,12,1,10,1,2,6,13,2,2,11,3,2,12,2,3,9,7,10,13,12,10,12,k,10,1,9,13,5,4,11,10,4,8,10,12,12,7,9,5,12,5,7,12,3,6,1,12,2,2,4,3,6,9,12,12,1,10,8,4,4,11,12,11,10,10,5,10,8,8,7,7,8,2,3,1,10,9,3,9,12,13,10,1,1,5,10,4,5,8,10,5,13,5,4,13,1,12,8,2,8,12,12,10,11,8,6,8,5,6,8,1,11,9,13,1,9,4,10,7,12,7,11,11

(1) Is there a pattern that repeats?
Answer: It's impossible to tell. There might be a pattern within the sequence of numbers you show; I'm not inclined to spend any time looking for it. But even if there is no repeating pattern in the numbers you show, it might be that there is a repeating pattern. For example, the entire sequence of numbers you show might be the repeating pattern; i.e., the next numbers in the sequence after the last number you show might be 2, 3, 5, 9, ....
(2) Is there a way to predict the next number in this string?
Answer: Not unless you know how the string is produced.
Without any context, it is pointless to try to determine the pattern in ANY sequence of numbers, even if only a few numbers are shown. And in fact, given any finite sequence of numbers, you can choose ANY number for the next number in the sequence, and it will be as good and as valid an answer as any other number.
So unless a problem like this has some context to give you a significant clue as to how the sequence is formed, it is a waste of time to try to figure out any problem like this.

Let me tell you one story, which I read somewhere many years ago . . . (just do not remember where).
It was during World War I.
German army was in a broad offensive.
French army was retreated.
Then the French aviation scattered fly-sheets with similar puzzles over the German army.
The German soldiers started collecting these fly-sheets; stopped their attack; and started solving the puzzles.
The German attack was stopped, in this way.
As a conclusion, I want to say that your puzzle suits very well for such a purpose !
(and doesn't suit for anything else).
