How to use the prompted value in the filter expression

Question

Hi
Is it possible to use the prompted value in the filter expression?
My requirement is that user will be prompted for a date field and I need to filter the records such that the records are displayed for the last 5 weeks from the date entered by the user.
If somehow I know how to use the prompted value in the filter expression then this requirement is easy to be done. If this is possible, please guide me?
If there are other ways to acheive the desired results then please suggest.
Thanks

SQL> create table tb_test

  3  , tot number(5)
  4  , mon_tot number generated always as (tot*15) virtual

Table created.
SQL> insert into tb_test (id, tot) values (1, 5);
1 row created.
SQL> select * from tb_test;
        ID        TOT    MON_TOT

  3  where  id = 1;
