高考数学试题中数列及数列极限是年年必考的内容,而且多是常规题,难度小、易得分。主要考查内容可概括为:①等差、等比数列的基本运算,②等差、等比数列的性质及其应用,③数列的通项,④数列的求和,⑤数列的应用,⑤数列极限及应用。要解答好高考试题中的数列及极限题,必须扎实牢固地掌握数列和数列极限的基础知识,特别是等差、等比数列的通项、中项及前n项求和公式,等差、等比数列性质,研究并熟练掌握数列及极限常见题型的解法与技巧,并能与其
In the mathematics test of the college entrance examination, the series and the limit of the series are the contents that must be checked every year. Most of them are regular questions, and they are difficult and easy to score. The main examination contents can be summarized as: 1 basic arithmetic of equal-difference, geometric progression, 2 equal-differences, the nature and application of geometric sequences, general term of 3 series, sum of 4 series, application of 5 series, 5 series Limits and applications. To answer the series and the limit questions in the high test questions, we must firmly and firmly grasp the basic knowledge of the limits of the series and the series, especially the arithmetical equations, the general term, the middle term, and the first n sum formulas of equal numbers, and the difference, Comparing the properties of the sequence, studying and mastering the solutions and techniques of series and extreme common questions, and
