Our problem contains 2 (M+ N+ 1) different orders and six different numbers of q in derivatives and integrals. The problem contains separate nonlinear functions. To examine existence and uniqueness results of the problem, Banach�s contraction principle and the Leray�Schauder nonlinear alternative are employed. An illustrative example is also provided. � 2018, The Author(s).All Open Access; Gold Open AccessExistenceq-derivativeq-integralq-integrodifference equationArticleScopus
