There are two well-known generalizations of Cesàro summation: the conceptually simpler of these is the sequence of (H, n) methods for natural numbers n. The (H, 1) sum is Cesàro summation, and higher methods repeat the computation of means. Above, the even means converge to ​1⁄2, while the odd means are all equal to 0, so the means of the means converge to the average of 0 and ​1⁄2, namely ​1⁄4.[9] So 1 − 2 + 3 − 4 + ... is (H, 2) summable to ​1⁄4.
