数列,特别是等差数列与等比数列,有着较为广泛的实际应用。在本章中,学生将通过具体实例形成数列的概念,掌握有关的公式,并运用公式解决一些简单的实际问题。数列在整个中学数学教学内容中,处于一个知识汇合点的地位,很多知识都与数列有着密切联系,过去学过的数、式、方程、函数、简易逻辑等知识在这一章均得到了较为充分的 The series, especially the arithmetic series and the geometric series, has a wide range of practical applications. In this chapter, students will form the concept of series through specific examples, master the relevant formulas, and use formulas to solve some simple practical problems. In the middle school mathematics teaching content, the sequence is in a position of knowledge convergence. Many knowledge is closely related to the sequence. The knowledge of numbers, equations, equations, functions, and simple logics learned in the past has been relatively good in this chapter. Full
