Question 1

Soln.
Ans: D

Midpoint is 10. We have to find 20 - 8 - 5 = 7 + 1th item from the left side. Since the location lies in the left half, the sequence has been reversed in this zone. So the item will be at location 10 - 7 = 3 + 1 from the left in the original series. Which means the item is: +.
