在高中数学的各个知识点中,最活跃,联系最广的应该是数列,在每年的高考试题中,数列约占总分的15%-20%,而通项公式又是数列的灵魂,因此,如何能在题目的背景中挖掘出通项的特点,将会是解数列问题的关键.下面仅就如何利用递推公式来求数列的通项做一下小结,供同学们参考.一、两点说明 Among the various knowledge points in high school mathematics, the most active and most connected are the series. In the annual high examination questions, the series accounts for about 15%-20% of the total score, and the general formula is the soul of the series. How to dig out the features of the general items in the background of the topic will be the key to solving the problem of numbers. The following is only a summary of how to use the recursive formula to find the general items of the series for the students to refer to. Point description
