摘要
受两个特殊周期数列和拉格朗日多项式的启发,给出一般周期数列的通项公式,从而解决了已知一个周期片段的任何周期数列的通项公式问题.
Enlightened by two interpretations on special cycle sequence and Lagrange's interpolation formula, the author finds a common generic formula of general term for cycle sequence. Meanwhile, the generic formula of general term for cycle sequence with a given intact period is provided.
