In the alphabet series BCD, EFG, IJK, NOP, TUV, which of the following three-letter groups should come next to continue the pattern logically?

Introduction / Context:
This is a three-letter alphabet-series question where each term appears to be a small block of consecutive letters. The sequence BCD, EFG, IJK, NOP, TUV must be extended by one more block selected from the options. These questions test a candidate's ability to track jumps in the starting letters and recognise simple continuous patterns within each block.

Given Data / Assumptions:

• Given series: BCD, EFG, IJK, NOP, TUV, ?.• Each term is a three-letter ascending block, for example B, C, D.• Starting letters are B, E, I, N, T.• We assume there is a regular increment in these starting letters.

Concept / Approach:
The letters inside a term are straightforward: they are consecutive. The trick lies in the changing starting letters. We convert B, E, I, N and T into their numerical positions, then look for a pattern in the differences between successive starting letters. Once the increment is identified, we apply it to T to find the next starting letter and then form the next three-letter ascending term.

Step-by-Step Solution:
Positions of starting letters: B=2, E=5, I=9, N=14, T=20.Differences are: 5 − 2 = 3, 9 − 5 = 4, 14 − 9 = 5, 20 − 14 = 6.Thus the increments follow the pattern +3, +4, +5, +6.The next increment should be +7.So the next starting letter = 20 + 7 = 27, which cycles to 1 after subtracting 26, giving A.Once the starting letter A is obtained, the next term is the ascending block ABC.

Verification / Alternative check:
Rewriting the starting letters and their increments confirms the pattern: 2→5 (+3), 5→9 (+4), 9→14 (+5), 14→20 (+6), and then 20→27 (conceptually +7) which maps to A. The internal structure of each term (three consecutive letters) is preserved by ABC. None of the other options satisfies both the correct starting-letter pattern and the ascending-triplet requirement.

Why Other Options Are Wrong:
YZZ and ZZB do not provide three strictly consecutive letters. Moreover, their starting letters do not match the next expected starting position after T. Repeating BCD would send the sequence backward rather than forward and break the clearly increasing pattern in the starting letters. Therefore, ABC is the only appropriate continuation.

Common Pitfalls:
Candidates sometimes ignore the variable increments between starting letters and assume a constant difference. Another mistake is to consider terms like YZZ which may look visually close to the end of the alphabet but do not actually form a neat consecutive block. Always verify that the internal structure and the starting-letter progression are both maintained.

Final Answer:
ABC
