数列是高考数学的重点与热点内容,高考对数列的考查非常全面,既有对等差数列、等比数列定义、性质的考查,又有对数列与指数函数、对数函数和不等式的综合考查,还有把极限思想和数学归纳法融入等差数列、等比数列中进行考查。新课标高考关于数列考点的命题,主要有以下几个方面:(1)对数列有关定义、等差数列、等比数列基本性质、基本运算的考查,常以选择题、填空题的形式出现,属容易题;(2)由简单递推式求数列的通项公式,进而求数列的前n项和,考查化归思想
The number of columns is the focus of college entrance examination mathematics and hot content, college entrance examination on the sequence of numbers is very comprehensive, both pairs of equal difference, the definition of geometric series, the nature of the test, and logarithmic and exponential functions, logarithmic function and inequality of the comprehensive examination , As well as the limit of thought and mathematical induction into the arithmetic sequence, the ratio of the series to examine. The new college entrance examination entrance examination on the number of columns proposition, mainly in the following areas: (1) the definition of the series, the arithmetic sequence, geometric series, the basic operation of the exam, often multiple choice, fill in the blank form , Is easy; (2) by a simple recursive formula to calculate the number of columns, and then seek the first n items and columns, test the return to thought
