Letter series pattern analysis – UGC NET Question

Statement A is correct because many letter series rely on letter positions (for example, A = 1, B = 2, etc.). Statement B is true since fixed forward or backward jumps are common. Statement D is also correct, as pairing or tripling letters often exposes a repeating cycle. Statement C is false because some series rely on reversing groups or cyclically shifting blocks, not just simple position changes. Statement E is false as NET papers do contain mixed letter–number series. Thus, the combination that includes A, B and D while excluding C and E is the only fully correct one.

Option A:
Option A is incorrect because it includes E, which wrongly claims that mixed letter–number series are never used, and therefore combines true and false statements. Even though A, B and D are correct, the presence of E makes this option invalid.

Option B:
Option B is wrong since it includes C, which falsely insists that only alphabet positions are ever used and bans reversals or rotations, and it omits D, which is a true strategy about grouping letters. This mix of one false and one missing true statement invalidates the option.

Option C:
Option C is also incorrect because it takes B, C and D together; C is false and the option leaves out A, which is an important fact about using letter positions. Including a wrong statement and omitting a true one makes the combination unsuitable.

Option D:
Option D is correct because it brings together A, B and D, all of which describe genuine features and methods for analysing letter series, while excluding the clearly false generalisations C and E.
