How to pass a sequence by 'using' for execute immediate

Question

how i can pass a sequence.nxlval as a parameter through using , here is my code looks like
sql_string is -> insert into some_tab (col1,col2, ....) (select col1,:passed_seq,......) where .... (i want to insert sequence values for col2)
and i am calling this as
passed_seq := 'seq_'||some_dynamic_num||'.nextval' ( in my db there will be sequences with the formed string like seq_10.nextval)
EXECUTE IMMEDIATE sql_string using passes_seq;
if i am doing like this i am getting
Error : -1722:ORA-01722: invalid number seq_10.nextval

Hi,
I hope you have created sequence as below
SQL>
SQL> CREATE SEQUENCE seq
  2  MINVALUE 1
  3  START WITH     1
  4  INCREMENT BY   1
  5  NOCACHE
  6  NOCYCLE;
Sequence created.
SQL>
SQL> SELECT * FROM TEST1;
     EMPNO EMPTYPE              EMP_ADDRESS              SALARY     DEPTNO
         1 HR                   MUMBAI                    10000         10
         2 ADMIN                THANE                      6000         20
SQL>
SQL> INSERT INTO TEST1 (EMPNO)
  2  VALUES(SEQ.NEXTVAL);
1 row created.
SQL> COMMIT;
Commit complete.
SQL> SELECT * fROM TEST1;
     EMPNO EMPTYPE              EMP_ADDRESS              SALARY     DEPTNO
         1 HR                   MUMBAI                    10000         10
         2 ADMIN                THANE                      6000         20
         1
SQL>Now if you need to add different numbe in differenct condition then create multiple sequence and use them accounding.
