In this article, we aim to present generalized results related to the well-known Hermite-Hadamard dual inequality for two distinct types of \ ( (, ) \) convex functions, employing various techniques such as Hölder's and Power mean inequalities. Consequently, both established and new results will be encompassed as special cases. Additionally, we intend to explore some relationships between our findings with well-known special means and trapezoidal formula.
