数列通项式求解方法

Grobe on the Solutions of General Form of Sequence of Number

求数列通项式，在中等学校数学教学中是一个难点，又占有一定的重要位置．笔者就数列通项式的求解方法归纳整理为累加法、递推式法、数学归纳法和待定系数法，提出了典型例子，并就待定系数法进行了较深入的探讨．

Finding general forms of sequence of number is a hard problem and has a important role to some extent in middle maths. This paper gives some methods about the sdutions of general form of sequence of number.
