Abstract

In this paper, we provide proofs of two 5ψ5{}_5\psi_5 summation formulas of Bailey using a 5ϕ4{}_5\phi_4 identity of Carlitz. We show that in the limiting case, the two 5ψ5{}_5\psi_5 identities give rise to two 3ψ3{}_3\psi_3 summation formulas of Bailey. Finally, we prove the two 3ψ3{}_3\psi_3 identities using a technique initially used by Ismail to prove Ramanujan's 1ψ1{}_1\psi_1 summation formula and later by Ismail and Askey to prove Bailey's very-well-poised 6ψ6{}_6\psi_6 sum.
