Hi,
You will have the follow the same sequence of restore as per the backup sequence. Skipping a TL-Log backup in between will report an error stating that LSN 340000001 for newer backup cannot be restored unless the backup for LSN 30000001 has been restored.
SQL server tracks the backups as per LSN. For each TLbackup an LSN is recorded. For every restore the continuity of LSN is ensured.
Thanks,
