Its a nice series of problems and i think there are more than enough untied problems for another Sequence and Series problem group. So maybe Chris its about time to curate one :)
Thanks Nikolaos. I was thinking of making a group on primes, but one on sequences and series is a good idea.
I'm interested to see whether anyone uses my approach to this problem--especially after all of the solvers of my Connell sequence problem (Cody Problem 46615) to this point found the easy way.
