Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? BEG, CFH, DGI, EHJ,?
FGK
FIK
FKL
FGL
FIK
Analyze the pattern for each column of letters independently. The first letters increase by +1 (B, C, D, E, F), the second letters increase by +1 (E, F, G, H, I), and the third letters increase by +1 (G, H, I, J, K).
Analyze the pattern for each column of letters independently. The first letters increase by +1 (B, C, D, E, F), the second letters increase by +1 (E, F, G, H, I), and the third letters increase by +1 (G, H, I, J, K).
Analyze First Letters
Look at the first letter of each term: B (2), C (3), D (4), E (5). Each letter is obtained by adding +1 to the previous first letter. Following this pattern, E + 1 = F (6).
Analyze Second Letters
Look at the second letter of each term: E (5), F (6), G (7), H (8). Each letter is obtained by adding +1 to the previous second letter. Following this pattern, H + 1 = I (9).
Analyze Third Letters
Look at the third letter of each term: G (7), H (8), I (9), J (10). Each letter is obtained by adding +1 to the previous third letter. Following this pattern, J + 1 = K (11).
Combine Letters
Combining the next letters (F, I, K) gives the term FIK, which matches Option B.
A: FGK is incorrect because the second letter should be I, not G. C: FKL is incorrect because the third letter should be K, not L. D: FGL is incorrect because both the second and third letters are wrong.
B is correct because each letter in the triplet increases by +1 position in alphabetical order (EHJ + 1,1,1 = FIK).
For letter cluster series questions, always check each column (1st, 2nd, and 3rd letters) independently for arithmetic progressions.
