UPSC CAPF – 2014
Observe the letters at odd positions (1st, 3rd, 5th, 7th, 9th): A, B, C, D, ?
This is a simple alphabetical sequence starting from A (1st letter of the alphabet), incrementing by one letter each time. The 9th letter in the overall series is at the 5th odd position, so it should be the 5th letter of the alphabet, which is E.
Observe the letters at even positions (2nd, 4th, 6th, 8th): C, E, G, ?
This is a sequence starting from C (3rd letter), incrementing by two letters each time (C+2=E, E+2=G). The 8th letter in the overall series is at the 4th even position. The sequence is C(3), E(5), G(7), I(9). The 4th letter in this sequence is I.
Combining these, the 8th letter is I and the 9th letter is E. The series continues as A C B E C G D I E.
