    The authors consider equivalence between the convergence for the modified Picard iteration, the modified Mann iteration, and the modified Ishikawa iteration. All those modified iterations are for \(L\)-Lipschitz mappings, Banach contractive mappings, nonexpansive mappings, and asymptotically nonexpansive mappings in Banach spaces. Some conditions related to positive series are proved to be sufficient for the mentioned equivalence.
