I tried using x = n, but it didn’t work. I also checked the help center about piecewise functions, but didn’t find a solution

This type of question may be better suited for the calculator support at [https://help.desmos.com/hc/en-us](https://help.desmos.com/hc/en-us). However, it looks like you’ve got a warning on your list, n. It probably has to do with the number of periods. You have two and you need three to define a series. The initial comma is not incorrect, but is not necessary. Either `[a,...b]` or `[a...b]` should fix your issue.
