Abstract: Mixed type functional equation is a further step of development in the broad area of functional equations. Many researchers introduced, various mixed type functional equations like additive-quadratic, quadratic-cubic, quadratic-quartic, additive-quadratic-cubic and so on. But even today notably, we have only one famous mixed type of additive-quadratic-cubic-quartic functional equation. In this study, the researchers made an attempt to introduce such new mixed type of additive-quadratic-cubic-quartic functional equation with its general solution and various stabilities related to Ulam problem in modular space.
