• Newton’s divided difference interpolation formula is used when the values of the independent variable are

Not equally spaced

Newton’s divided difference interpolation formula is a interpolation technique used when the interval difference is not same for all sequence of values. Divided differences are symmetric with respect to the arguments i.e independent of the order of arguments.
