How to create incremental numbers in InDesign or Illustrator?

I normally use "Data Merge" in InDesign and use Excel (or something like it) to generate the list of numbers for me. You would copy the numbers into a text file so that InDesign can read them as the merge data source. Note that you would have one ticket on the page and then let InDesign set the other tickets on the page (you can tell the Data Merge control panel about spacing).

You can also get creative with "Bullets and Numbering" -- but I haven't tried that.

The nice part of using Data Merge is that you can also put in sections, prices, etc. and have those change according to the seat -- then save the text file and use it next season.
