On the Arithmetic Series
of Geometric Teaching Methods
Abstract：In this paper, a brief introduction of two aspects are given, which are the teaching methods of arithmetic progression and geometric proportio as well as the sum of the first n items of arithmetic progression and geometric proportio,aimed at the fetures,difficult points and teaching goals of the arithmetic progression and geometric proportio in the current teaching ,espically the derivations and applications of the sum of the first n items about arithmetic progression and geometric proportio. This article also introduces how to transform the primary data to the practical problem, how to exercise student's inferential reasoning question ability, how to exercise student's mathematics thought ,how to use the formula in the real life and some other related knowledge.
