Newton's Forward Difference Formula
https://math.iitm.ac.in/public_html/sryedida/caimna/interpolation/nfdf.html
The formula is called Newton's (Newton-Gregory) forward interpolation formula. So if we know the forward difference values of f at x 0 until order n then the above formula is very easy to use to find the function values of f at any non-tabulated value of x in the internal [a,b].The higher order forward differences can be obtained by making use of forward difference table.

Finite difference - Wikipedia
https://en.wikipedia.org/wiki/Finite_difference
Finite difference is often used as an approximation of the derivative, typically in numerical differentiation. The derivative of a function f at a point x is defined by the limit. If h has a fixed (non-zero) value instead of approaching zero, then the right-hand side of the above equation would be written
