In this paper, a new mixed-type higher-order symmetric duality in scalar-objective programming is formulated. In the literature we have results either Wolfe or Mond-Weir-type dual or separately, while in this we have combined those results over one model. The weak, strong and converse duality theorems are proved for these programs under η-invexity/η-pseudoinvexity assumptions. Self-duality is also discussed. Our results generalize some existing dual formulations which were discussed by Agarwal et al. (Generalized second-order mixed symmetric duality in nondifferentiable mathematical programming. Abstr. Appl. Anal. 2011. https://doi.org/10.1155/2011/103597), Chen (Higher-order symmetric duality in nonlinear nondifferentiable programs), Gulati and Gupta (Wolfe type second order symmetric duality in nondifferentiable programming.
