The n-th partial sums below are true for each positive integer n.

- (I)

- (II)

The notationsandin (I) and (II) represent the special values of a new generic formula that we define it as an extensive notation from Hurwitz zeta function [1*] for n-th partial sum as follows

,

where s and a are complex variables with Re(s) > 1 and Re(a) > 0.

When n tends to infinity, the extensive notation [2*] is then expressed as

.

**Special Case**

- n = ∞:

In the limit as n approaches to infinity, both series (I) and (II) converge and its values are

, where is Apéry's constant.

.

**Example**

- If we put n = 2, both sides of (II) are equal to 29/31752, namely

.

[2*] The purpose of our website is to show a beauty of series. We introduce a new extension of the notation of Hurwitz zeta function for n-th partial sum because there exist such series (I) and (II). We share our results on the internet. The acceptance of this notation is the work of other men.
