You don't have one list here: you have two. The
Text here... is a separate paragraph and that's not something you can have within a single list. The best that you can do, I think, is to tell your second list numbering to start with 3 (see the
[@3] construct below), but note that if you add a third element to the first list, you will need to tweak the beginning number of the second list manually:
1. Question 1
2. Question 2
3. [@3]Question 3
See the manual for details.
EDIT: as the OP points out in the comments, this does not work in 9.1.9. The bug was fixed about a year ago:

ox-odt: Add support for text:start-value
* lisp/ox-odt.el (org-odt-item): Support starting lists at a set
number via "text:start-value". Without this, ODF files just restart
numbering when they should continue with the specified number.

This fix went in to 9.1.15. IOW, upgrade!
