Re: trending growth, next increment

daily snapshot (or as you like):

insert into db_growth_tbl
select file_name, file_id, tablespace_name, bytes/1048576 size_MB, trunc(sysdate) snap_date
from dba_data_files;

use sql analytical functions to process the results on weekly, monthly, quarterly, yearly basis...:-)
