数列是高中数学的重要内容之一,在高考中占有重要的地位,特别是对等差数列,等比数列的考查,更是“常考常新”．客观题多为与基本量有关的中低难度题,主要考查等差数列、等比数列的概念与性质灵活运用;解答题多为中等以上难度的综合题,经常把数列知识和函数、不等式、解析几何等知识综合起来,以递推关系为条件或结论,突出考查考生的思维能力, The series is one of the important contents of high school mathematics, and it occupies an important position in the college entrance examination, especially for the equal-difference series, and the examination of the geometric series is more often than not. The objective questions are mostly medium and low-level questions related to the basic quantity. The main test is to use the concepts and properties of equal numbers and geometric progressions flexibly; the answer questions are mostly comprehensive problems with medium or more difficulty, often with series knowledge and functions, inequalities, Analytic geometry and other knowledge are combined together, and recursive relations are used as conditions or conclusions to highlight examinee’s thinking ability.
