@rschwieb funny that you had a conversation with Bill today. He flat out said in a post to one of my posts that he had been temporarily banned from chat and that this ban was the last straw of many and he was leaving the site... I have no clue why he messaged me of all people to say this to. I find it strange that @BillDubuque has seemingly returned. Very confused. Going to go make metaphorical popcorn. Nobody is welcome to join me.

Convergence of positive sequence in which each term is less than the average of preceding 2 terms is a duplicate of this more general question. Unfortunately, I found that only after solving the general case myself.

(Also I had to retract a close-vote, therefore I cannot close-vote as a duplicate anymore.)
