一个数列,在具体的给出之前,人们可以充分的发挥自由想象去创造它,设计它.如:设定它的首项是一个什么数,它的变化规律又是如何.正如文学作品的创作一样,作者可以任意发挥自由想象,去描述主人翁的出生,讲述他的成长过程.从这个角度去分析,就清楚表明:中学数学具有文化性质.也就 Before a specific series is given, people can fully use their free imagination to create it and design it. For example, what is the number of the first item and how it changes is just like the creation of a literary work. In the same way, the author can arbitrarily play his free imagination to describe the birth of the master and tell him about his growing up. From this perspective, it is clear that: high school mathematics is of a cultural nature.
