Getting position of data after selecting

Question

Hi All,
Need help regarding this...
Say I have a select statement that selects data from it and orders it in some fashion...
Ex:
The list of top 5 earners in a organisation
i.e SELECT ename,sal FROM EMP WHERE sal >(SELECT AVG(sal) FROM EMP) AND ROWNUM<=5 ORDER BY sal DESC;
gives a list say
ename sal
A 5000
B 3000
C 2000
...... and so on ..
is it possible to add one more column and create a view which gives the position of each employee after selecting
say...
ename sal position
A 5000 1
B 3000 2
C 2000 3...
Can anybody help me out please...
so that wn I say position 2 it should give me 'B' as my ename

SQL> SELECT first_name, last_name, salary, rn_sal sal_position
  2    FROM (SELECT e.first_name,
  3                 e.last_name,
  4                 e.salary,
  5                 AVG(salary) over() avg_sal,
  6                 row_number() over(ORDER BY salary DESC) rn_sal
  7            FROM hr.employees e)
  8   WHERE salary > avg_sal
  9         AND rn_sal <= 5
10   ORDER BY rn_sal;
FIRST_NAME           LAST_NAME                     SALARY SAL_POSITION
