有穷数列通项公式的三种通用求法

Three Common Ways on the General Term of a Finite Sequence of Number

本文推广并证明了Lagrange插值公式.通过对Lagrange插值公式的证明,阐明了有穷数列通项公式的存在性和不唯一性,并进一步给出了通项公式的三种通用求法.

This paper generalizes and demostrates Lagrange formula, through which the paper reveals the existence and the diversity of a finite sequence of number. Consequently, three practical ways for a general term are offered.
