生成数列

Generating Sequences

根据项与项之间的规则(如“每次加3”)或项的位置与项的数值之间的规则(如“2n + 1”)生成数列的项,并判断数列是等差数列、等比数列,还是其他类型。

Generate terms of a sequence from a term-to-term rule (e.g., 'add 3 each time') or a position-to-term rule (e.g., '2n + 1'), and identify whether a sequence is arithmetic, geometric, or neither

{{name}}能否算出像 5, 8, 11, 14……这样的数列接下来的几项,并说明它的规则是“每次加一个固定的数”还是其他规则?

Can {{name}} work out the next few terms of a sequence like 5, 8, 11, 14… and explain whether the rule is "add a fixed number each time" or something else?
