In this paper we prove the convergence of arithmetic means of sequences generated by a periodic function   $\varphi (X)$ , moreover if
 $\varphi (X)$ , moreover if   $\varphi (X)$  satisfies a suitable symmetry condition, we prove that their limit is
 $\varphi (X)$  satisfies a suitable symmetry condition, we prove that their limit is   $\varphi (0)$ . Applications of previous results are given to study other means of sequences and the behaviour of a class of recursive series.
