Yes the max sequence generated on primary is same as the max sequence applied on standby.
And what is MRP and why it is important can you please let me know abt thisWhenever you created standby database, Make a habit of tail to alert log file to monitor whats happening on the standby database, Besides MRP is an Media Recovery Process , which applies archies/redo on standby database.
MRP can apply based on the redo transport, If you are using real-time apply then Redo will be writtened to the standby redo log files at the same time recovery will be performed by MRP process, If you are not using Real-Time apply then whenever a archive generated on primary that archive will be transported to the standby and applied on the standby database.
It is recommended to use Realtime apply, so that you can avoid much data lost.
However you are in 11gR2, You can use below query to monitor
SQL> SELECT * FROM V$STANDBY_EVENT_HISTOGRAM WHERE NAME = 'apply lag'  AND COUNT > 0;
NAME             TIME UNIT                  COUNT LAST_TIME_UPDATED
apply lag           0 seconds                 431 08/05/2012 22:14:21
apply lag           1 seconds                   7 08/05/2012 22:13:31
