Milne’s predictor-corrector (P-C) method is a multi-step method where we assume that the solution to the given initial value problem is known at past 3 equally spaced points.

Thus, the correct answer is 3.

Milne’s method uses information from three previous points to predict the next value, making it a third-order method in terms of accuracy.
