We propose to derive the explicit multistage methods of the Runge-Kutta type for ordinary differential equations (ODEs) with the aid of the expansion of grid functions into the Lagrange-Burmann series. New explicit first- and second-order methods are derived, which are applied to the numerical integration of the Cauchy problem for a moderately stiff ODE system. It turns out that the L2 norm of the error of the solution obtained by the new numerical second-order method is 50 times smaller than in the case of the classical second-order Runge-Kutta method.
