• Are the 8 sequences related? Or are they separate? – Dr Xorile Nov 12 '18 at 22:53
• They are separate. :) – danimoth Nov 13 '18 at 3:40
• Mmm. That makes this extremely difficult. You might find it gets closed as too broad. It becomes a "guess what's in my head" if there's no connecting theme. – Dr Xorile Nov 13 '18 at 4:13
• I believe the OP means that the eight sequences follow the same algorithm, but in different cases – Omega Krypton Nov 13 '18 at 7:39
• Hmmm, I wonder what the 7th one is? I know! 5! (just joking) – Yout Ried Jan 5 at 5:48
