p-Stable hybrid linear multistep methods (HLMMs) have been a fascinating area of interest for the numerical solution of second order initial value problems in ordinary differential equations, because of their high order of accuracy.

We give a theorem with proof, stating the limitation of the approach in search for higher order p-stable formulas. We carry out several numerical experiments to validate the accuracy and superiority of our schemes over some existing methods in the literature.
