This study presents two efficient iterative methods for solving nonlinear equations using Adomian decomposition technique and a quadrature rule. The proposed methods are free of second derivatives and exhibit a higher order of convergence through a predictor-corrector scheme. Their effectiveness is verified by testing them on various mathematical models and comparing their performance against several well-known methods. Graphical analysis is also presented to validate the numerical results.
