数列是高中数学的重要内容,是初等数学通往高等数学的桥梁.因此,无论是从有利于中学数学教学出发还是从有利于高校选拔人才出发,数列都是永不衰退地高考热点.纵观近年高考试题,数列试题的分数年年都占二十分左右,且试题不落俗套,新花样层出不穷.本文将以近年高考试题为例,分别阐述几类热点问题的求解,供参考.
The series is an important part of high school mathematics, and it is a bridge between elementary mathematics and advanced mathematics. Therefore, whether it is from the perspective of favoring middle school mathematics teaching or from favoring the selection of talents in colleges and universities, the series is always a hot spot for college entrance examinations. In recent years, the exam questions have scores of about twenty percent each year, and the questions are not unconventional. The new tricks are endless. This article will take the exam questions in recent years as an example to illustrate the solution of several hot issues, for reference.
