数列与递推是高中数学的一大重要部分,无论高考还是竞赛,都是重中之重。我们从小学开始就接触数列,“找规律”之类的数字游戏其实就是最基本的递推,初中又学习了基本的数列:等差数列和等比数列,而高中的数列与递推的难度远大于以前,因此,准确掌握并能熟练应用是当下一项重要的任务。下面我推荐了一阶线性递推的几种方法,以帮助大家解决问题。 Numbers and recurrences are an important part of high school mathematics. Regardless of the college entrance examination or competition, it is a top priority. We touched the series from the beginning of elementary school. Digital games such as “finding the rules” are actually the basic recursive. The junior high school also learned the basic sequence: arithmetic progressions and geometric progressions, and the high school progressions and recurrences. The difficulty is far greater than before, so accurate mastery and proficiency in application is an important task of the moment. Below I recommend several methods of first-order linear recursion to help everyone solve the problem.
