It is really important to be acquainted with the restore sequence of restoring a full database backup.
You need to restore the full backup, differential database backup, and all transaction log backups WITH NORECOVERY option. Then, bring back the database online using the WITH RECOVERY option.
Here is a Sample restore sequence:
RESTORE DATABASE FROM full_database_backup WITH NORECOVERY;
RESTORE DATABASE FROM differential_backup WITH NORECOVERY;
RESTORE LOG FROM log_backup WITH NORECOVERY;
-- Keep repeating it until you restore log backup
RESTORE DATABASE WITH RECOVERY;
