A new proof for a nonterminating "strange" hypergeometric evaluation of Gasper and Rahman
Abstract
An elementary proof is given for a nonterminating "strange" cubic 7F6-series summation formula of Gasper and Rahman, through the modified Abel lemma on summation by parts. As a byproduct, an interesting nonterminating 3F2(3/4)-series identity conjectured by Gosper, is also rederived.
