NO, you dont need to DROP the sequence, here is demo code i used to reset a sequence(this resets it back to 1).

SQL> drop sequence test_seq;

Sequence dropped.

SQL> create sequence test_seq;

Sequence created.

SQL>
SQL> declare
  2 seq_hold_var number;
  3 begin
  4 for i in 1 .. 100000 loop
  5 select test_seq.nextval into seq_hold_var from dual;   6 end loop;
  7 end;
  8 /

PL/SQL procedure successfully completed.

SQL>
SQL> select test_seq.nextval from dual;

NEXTVAL

100001

SQL>
SQL> alter sequence test_seq increment by -100000;

Sequence altered.

SQL>
SQL> select test_seq.nextval from dual;

NEXTVAL

SQL>
SQL> alter sequence test_seq increment by 1;

Sequence altered.
