You can't, but you could add the alphanumeric part in the trigger code to populate the field:

:NEW.your_column := 'ABC'||your_sequence.nextval;

If you want to generate alphanumeric characters sequentially, you could think of it as generating integers as normal then converting them to base 36. There is an example here.
