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

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 9 10 11 2 3 4 5 6 7 8 9 10 11 12 3 4 5 6 8 9 10 11 12 13 2 4 6 7 8 9 10 11 12 1 3 14 3 5 6 7 9 10 11 12 13 14 15 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 4 5 7 8 10 11 12 13 14 15 16 17 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 3 6 7 8 9 11 12 13 14 15 16 17 18 19 2 4 5 6 8 9 10 11 12 13 14 15 16 17 18 19 20 3 4 5 6 7 8 9 10 12 13 14 15 16 17 18 19 20 21 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 5 7 9 10 11 13 14 15 16 17 18 19 20 21 22 23 2 3 4 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 3 4 5 6 7 8 9 10 11 12 14 15 16 17 18 19 20 21 22 23 24 25 2 4 5 6 7 8 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 3 5 6 8 9 10 11 12 13 15 16 17 18 19 20 21 22 23 24 25 26 27 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
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
