| Abstract: | By showing the object background of the sum of natural number power series n terms the area of the trapezoid with curved sides and by presenting the process of extracting the sum of natural number power series n terms, this article revealed the internal connections between in- tegral and number series. At the same time, it reasoned out the recurrence formula of the sum of nat- ural number power series n terms. |
