If the second half of the following series is reversed, then which item is 5th to the left of the 2th item from the right side? The series is:
R C % W 2 K E S 4 Y L N T F M X G 5 $ Z
Midpoint is 10. We have to find 20 - 2 - 5 = 13 + 1th item from the left side. Since the location lies in the right half, the sequence has been reversed in this zone. So the item will be at location 10 + (20 - 13) = 17 + 1 from the left in the original series. Which means the item is: 5.
