Full question:

You want the ability to recover to any time within the last seven days and therefore you configured the recovery window retention policy using the command:

RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

After configuring the recovery window, you performed the database backup as follows:
– Backup RB1 at log sequence number 12871 on 5th Jan
– Backup RB2 at log sequence number 15622 on 12th Jan
– Backup RB3 at log sequence number 16721 on 15th Jan

On 20th Jan when the log sequence number was 18112 you realize that there is a need to recover to a point in time at the beginning of the recovery window. You have all archived redo log files to date.
