Inserting a sequence of numbers SQL

Question

I have a table 'Persons' which has a field 'ID' which is also a primary key. I tried this and I keep getting 'ORA-00933: SQL command not properly ended'. I'm a beginner at this. I'm using apex.

CREATE SEQUENCE idNmbrs INCREMENT BY 1 START WITH 100,
INSERT INTO Persons (ID) VALUES(idNmbrs.nextval);

Answer 1

CREATE SEQUENCE idNmbrs START WITH 100 INCREMENT BY 1;

INSERT INTO Persons (ID) VALUES(idNmbrs.nextval);
