另一种常用的定义序列的方法是，通过一串指令说明在给定出项后如何给出后面的各项。

Another common way to defined a sequence is by a set of instructions which explains how to carry on after a given start.

youdao

It's a long sequence of instructions, it starts at the beginning, walks through, may jump around a little bit, but eventually comes down at the end. It's okay for the things you're doing for the early problem sets.

这是一长串指令，从开端开始，向前步行，偶尔来回跳一会儿,但是最终会走到结尾,这些足以解决最初级的问题。
