Abstract: In this paper, we have given provided all the information “Newton’s forward and backward interpolation method”, as this method is used for equal intervals, and both forward and backward is applied. Which includes derivation, numerical solutions for both methods, differentiation between forward and backward methods, applications used in real life, and advantages and disadvantages, given with its result that which one is more efficient. We have also given the references we have used for this review paper.

Keywords: Newton’s Forward Method, Newton’s Backward Method, Mathematical Solution, Derivation, MATLAB Program, C++ Program, Differentiate between Forward and Backward.
