摘要
关于数列的研究历来为人们所关注，尤其是非线性递归数列通项的求解问题更是讨论的热点．由于递归数列与函数迭代有着密切关系，因此本文试图用函数迭代思想解决一类数列通项的求解问题．
equence research is always attention by people. Especially nonlinear recursion sequence is a focus of the discussion. Because recursion sequences are relevant to function alternate, the paper tries to solve the sequence of function alternate by alternate thought.
