ABSTRACT
A strange nonterminating -series formula was conjectured by Gosper and was confirmed subsequently by Gasper and Rahman, who evaluated another similar -sum. By means of the modified Abel lemma on summation by parts, we prove an analogous strange nonterminating -series summation formula, extending both a terminating -sum and a nonterminating -series evaluated by Chu through inverse series relations and the modified Abel lemma on summation by parts.
