Numbering in LibreOffice

 I was excited when I found out about LO, however I have a problem with regard to its numbering system. Here is an example. 
  1. What is your favorite food (1 being the highest and 10 being lowest).
  • 1
  • 3
  • 2
  • 6
    and so on…

  1. a.
    and so on…

  2. a.

  3. a.

So my question is this, how can I change its numbering into this type of sequence? TIA!

I have zero idea what your question is. Your example makes no sense to me. Sorry. (try again?)
