i create a sequence
ex: create sequence rr start with 1;
now i use this sequence in my reprts for the running serial number
as rr.nextval into a from dual;
here a is the field which gives the random sequence number.
first when i run the report a list of values as 1,2,3,4,.. gets inserted into the serial number column.
when i exit and run the file the number starts inserting from 5..

Sequence is an object whose value will be increased whenever you reference it by .NEXTVAL. This incremented value will be stored in the database and whenever you/ any other user tries to access the same, you/he will get an incremented value.
In your case, it seems a PL/SQL variable initialized with 1 and increamented by 1 after every INSERT statement will be sufficient. No need to use sequence if the value is not a primary key.
