Let ind(c) be the Morse index of a closed geodesiccin an (n+1)-dimensional Riemannian manifold. We prove that an oriented closed geodesiccis unstable ifn+ ind(c) is odd and a non-oriented closed geodesiccis unstable ifn+ind(c) is even. Our result is a generalization of the famous theorem due to Poincaré which states that the closed minimizing geodesic on a Riemann surface is unstable.
