| 摘 要： | 数列求和问题是高考中的重要内容之一,如何掌握数列求和方法至关重要。一般数列求和是对通项变形,将其转化成熟悉的数列求和问题,或利用代数式的对称性,采用消元等方法求和。依据对数列求和的认识和理解,通过不断积累,结合具体实例,本文主要对四种方法进行了分析研究。将这些方法恰到好处地运用在教学过程中,能帮助学生较快地吸收知识,掌握求解方法及技巧。

| Abstract: | The question of series summation is one of the important contents in the university entrance exam.So mastering the method of sum of sequence is very important.General series summation is achieved through deforming the general term and translating into familiar series summation,or uses its symmetry and elimination method to get series summation.The article analyzes and researches four methods.If the teachers utilize these methods into teaching process,it can help students to faster absorb knowledge and grasp the solving methods and skills. |
