An extension of a supercongruence of Long and Ramakrishna

We prove two supercongruences for specific truncated hypergeometric series. These include a uniparametric extension of supercongruence that was recently established by Long and Ramakrishna [Adv. Math. 290 (2016), pp. 773–808]. Our proofs involve special instances various identities including Whipple’s transformation the Karlsson–Minton summation.
