摘要
利用“差分”的概念研究了数列的性质,提出了一个新的算法——差分算法,导出了数列通项公式及部分和求和公式.
The relation between general term and section sum of sequence of number is studied. Using difference method, several general term formulas and some section sum formulas for sequence of number is given. The algorithm is simple and has low computational complexity. The numeral examples show the effectiveness of the proposed algorithm.
