一、概念学习的类比数列是一类特殊的函数,因此学习数列的有关概念时,可以类比函数,如数列与函数的概念、等差数列与一次函数、等比数列与指数函数、等比数列与等差数列等.教材在由各类具体实例概括抽象出数列的定义和有穷、无穷、递增、递减、常、摆动数列等分类后,从两个角度提出了数列概念和函数概念的类比,一是数 First, the concept of analogy learning sequence is a special type of function, so learn the concepts of the series, you can analogy, such as the concept of numbers and functions, arithmetic and linear functions, geometric and exponential functions, geometric series And arithmetic progression, etc .. The teaching materials abstracts out the definition of number sequence from various concrete examples and the classification of number concepts such as finite, infinity, increment, decrement, constant, swing and so on from several angles First, the number
