This is what you have, essentially:
5. a
- b
- c
d
- e
- f
g
- h
- i
- a: list item—numbered
- b list item—bullet nested in a
- c: list item—bullet nested in a
- d: plain text—paragraph
- e: code—first line of code e
- f: code—second line of code e
- g: plain text—first line of paragraph g
- h: plain text—second line of paragraph g
- i: plain text—third line of paragraph g
If you’re trying to nest all of those in a, then:
5. a
- b
- c
d
- e
- f
g
- h
- i
If you want each of d and g to be a new paragraph that introduces a new list, then:
5. a
- b
- c
d
- e
- f
g
- h
- i
Or are you going for something else?
