Abstract

In this paper, we consider and analyze several-step iterative methods for solving  nonlinear  equations. . This method is based on a direct Newtonian  interpolation of the function and modified Adomian’s decomposition.  We  prove  the important fact that methods obtained  preserve  their convergence order  3, without calculating any derivatives.  Some numerical illustrations are given to show the efficiency of algorithms.
