Furthermore, we obtain this iteration process is equivalent to Mann iteration method and converges faster than Picard-S iterative scheme. Also, we create a table and graphics to support this result. Moreover, we show that this iteration method can be used to solve a nonlinear integral equation. Finally, a data dependence result for the solution of this integral equation is proven. Keywords: Three step iteration, strong convergence, rate of convergence, data dependence integral equation. References: [1] F. Gursoy, V.
