r test_for_cursor%rowtype;
r1 test_for_cursor.i%type;

update test_for_cursor set i=r.i+2 where i=r.i returning i into r1;
dbms_output.put_line(r1);

Answer 1

Try this
DECLARE
   CURSOR cur_test
   IS
      SELECT     *
            FROM test_for_cursor
           WHERE i = &i
      FOR UPDATE;
   r    test_for_cursor%ROWTYPE;
   TYPE r1_typ IS TABLE OF test_for_cursor.i%TYPE;
   r1   r1_typ;
BEGIN
   OPEN cur_test;
   LOOP
      FETCH cur_test
       INTO r;
      EXIT WHEN cur_test%NOTFOUND;
      UPDATE    test_for_cursor
            SET i = r.i + 2
          WHERE i = r.i
      RETURNING i
      BULK COLLECT INTO r1;
      FOR j IN 1 .. r1.COUNT
      LOOP
         DBMS_OUTPUT.put_line (r1(j));
      END LOOP;
   END LOOP;
   CLOSE cur_test;
END;Some correction.
