Predictor–corrector method - Wikipedia
https://en.wikipedia.org/wiki/Predictor–corrector_methodWhen considering the numerical solution of ordinary differential equations (ODEs), a predictor–corrector method typically uses an explicit method for the predictor step and an implicit method for the corrector step. A simple predictor–corrector method (known as Heun's method) can be constructed from the Euler method (an explicit method) and the trapezoidal rule (an implicit method).

web.mit.edu › 10 › WebThe combination of the FE and the AM2 methods is employed often. Here, we use the FE as a predictor equation to get ypn+1and subsequently use the AM2 as a corrector equation to get the final computed solution yn+1. The method, referred to as the Euler-Trapezoidalmethod is given below.
