In terms of Sears’ transformation formula for \(_4\phi_3\)-series, we provide standard proofs of a summation formula for \(_4\phi_3\)-series due to Andrews [Andrews, Adv. Appl. Math. \(46 (2011), 15-24]\) and another summation formula for \(_4\phi_3\)-series conjectured in the same paper. Meanwhile, several other related results are also derived.
