In this paper, we study the existence of periodic solutions for autonomous nonlinear ordinary differential equations of order n. Our method is based on the evaluation of Brouwer's degree theory and making use of the homotopy invariance property of the topological degree and also suitable norm inequalities. For this, we prove two lemmas about the second and third order ODE systems and then present two theorems about the sufficient conditions for the existence of periodic solutions for the even and odd n-order ODE respectively.
