在中学代数中，数列通项是高中数列教学的重要内容之一。数列的相关知识在高中数学教学中占有相当重要的位置，正确而熟练地掌握数列的性质对于解决数列问题有很大的帮助。而数列的种类繁多, 形式复杂, 绝大多数既非等差数列, 又非等比数列。本文将通过以下几点来分析，首先分析有穷数列，主要是中学数学里的数列的性质及在高考中求解数列通项公式的常用方法，即（1）根据数列（主要是等差数列和等比数列）的定义及其性质与推论求数列通项公式。（2）由数列的递推公式求通项公式的方法；（3）求数列通项若干方法（无穷数列的通项公式），其次是研究高阶等差数列，用拉格朗日插值公式求数列通项公式等。

Answer 1

Algebra in middle school, high school series series of general term is an important part of teaching. Series of related knowledge in mathematics teaching in high school plays an important position, correct and a good command of number sequences to solve series of problems for the great help. The wide variety of series, complex form, the vast majority are neither arithmetic progression, but also non-geometric series. This article by the following analysis, the first analysis of finite series, mainly middle school mathematics in the number sequences and in the entrance to solve series of general formulas of the common methods, namely (1) According to the series (mainly arithmetic sequence and geometric sequence) of the definition and properties of numbers and reasoning find the general formula. (2) by the series of recursive formula general formula of seeking ways; (3) Find the general term of a number of methods series (infinite series of the general formulas), followed by the arithmetic sequence of order, with the Lagrange interpolation formula find the general formula of the number and so on.

In middle school in algebra, series the general term is high school sequence one of the important contents of teaching. Sequence related knowledge of mathematics teaching in high school occupies an important position

Answer 3

Algebra in middle school, high school series series of general term is an important part of teaching. Series of related knowledge in mathematics teaching in high school plays an important position, correct and a good command of number sequences to solve series of problems for the great help. The wide variety of series, complex form, the vast majority are neither arithmetic progression, but also non-geometric series. This paper will analyze the following points, the first of a series of poor, mainly in middle school mathematics and the nature of the series in the number of college entrance examination in the general formula for solving the common methods, Namely (1) According to the series (mainly arithmetic series and geometric series) of the definition and properties of numbers and reasoning find the general formula. (2) by the series of recursive formula general formula of seeking ways; (3) Find the general term of a number of methods series (infinite series of the general formulas), followed by the arithmetic sequence of order, with the Lagrange interpolation formula find the general formula of the number and so on.
