Whats the pattern? And what comes next? :)

• Did you make this yourself? Jul 21, 2016 at 9:36
• @Mithrandir I did. It comes from some research I have been doing into polygonal numbers, so thats a hint there. :) Jul 21, 2016 at 9:41
• Just making sure, because if you post something that you didn't make yourself without attribution, it's plagiarism. :P Jul 21, 2016 at 9:49
• Once this is solved you should consider adding it to the OEIS. Probably best not to do that before it's solved, though. (Of course once I see the solution I may change my mind about its appropriateness for OEIS...) Jul 22, 2016 at 9:24
• If my answer is correct then I think this (and some obvious "predecessors" to it) certainly do belong in OEIS. Jul 22, 2016 at 10:05
