Then we give the definition of the Gaussian modified Pell polynomial sequence, for n ? 2, by the relation = 2 + with initial conditions = 1? xi and = x + i. We give Binet’s formulas, generating functions and summation formulas of these sequences. We also obtain some well-known identities such as Catalan’s identities, Cassini’s identities and d’Ocagne’s identities involving the Gaussian modified Pell sequence and Gaussian modified Pell polynomial sequence....enAttribution-NonCommercial-NoDerivs 3.0 United Statesinfo:eu-repo/semantics/openAccessModified Pell sequenceModified Pell polynomial sequenceGaussian modified Pell sequenceGaussian modified Pell polynomial sequenceArticle21637210.29002/asujse.374128
