Look at the series: Z 7 @ 4 P % C 9 5 T E # 2 S 8 U & 6 A 3 W ! (22 elements). Which element is fourth to the left of the ninth element from the right end?

The ninth element from the right end stands at place 22 − 9 + 1 = 14, which is S. Four places to its left is place 10, holding T. E at place 11 is one step short of the mark and 2 at place 13 is three steps short; P at place 5 is where you finish if you take the ninth element from the LEFT (the 5 at place 9) and count four to its left.
