Or other way around can be rename the current sequence and
create new sequence with the desired values;

SQL> CREATE SEQUENCE SEQ_TET INCREMENT BY 1 START WITH 100
MAXVALUE 1000000 MINVALUE 99;

Sequence created.

SQL> rename SEQ_TET to seq_test;

Table renamed.

SQL> select * from user_sequences;

SEQUENCE_NAME MIN_VALUE MAX_VALUE
INCREMENT_BY C O CACHE_SIZE
------------------------------ ---------- ---------- -------
----- - - ----------
LAST_NUMBER
-----------
SEQ_TEST 99
1000000 1 N N 20
