One of the methods for summing series and sequences. The series is summable by the method of arithmetical averages to the sum if where . In this case, one also says that the sequence is summable by the method of arithmetical averages to the limit . The summation method of arithmetical averages is also called the Cesàro summation method of the first order (cf. Cesàro summation methods). The summation method of arithmetical averages is completely regular (see Regular summation methods) and translative (see Translativity of a summation method).
