I have a pattern of numbers, how can i find out how to get the same output

[devonrevenge]

So i want to get this output, see a pattern? how do you analyse a pattern to know how to get its sequence

2 3 2 3 4 4 5 2 3 4 5 6 3 5 6 7 2 4 5 6 7 8 3 4 6 7 8 9 2 3 4 5 6 7 8 9 10 5 7 8

It's less "analysis" and more "try another random function you've just conjured up and hope like hell it works this time".

Check Encyclopedia of Integer Sequences. I think that sequence is
"Triangle read by rows in which row n lists the proper non-divisors of n, or zero if n=<2":

its a real mathematicle sequence, apparently its simple, but i guess i could find a way to make it

[MiiNiPaa]

search for it on http://oeis.org
For example your pattern: http://oeis.org/search?q=2%2C+3%2C+2%2C+3%2C+4%2C+4%2C+5%2C+2%2C+3%2C+4%2C+5%2C+6%2C+3%2C+5%2C+6%2C+7%2C+2%2C+4%2C+5%2C+6%2C+7%2C+8&sort=&language=english&go=Search
