Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? BDE, DFG, FHI, HJK,?
JLM
JKL
IMN
KLO
JLM
Observe the first, second, and third letters of each cluster independently; each follows a consistent jump of +2 positions in the alphabet.
Observe the first, second, and third letters of each cluster independently; each follows a consistent jump of +2 positions in the alphabet.
Analyze First Letters
Looking at the first letters of each cluster: B(2), D(4), F(6), H(8). The pattern is +2. Therefore, the next letter is 8 + 2 = 10, which is J.
Analyze Second Letters
Looking at the second letters of each cluster: D(4), F(6), H(8), J(10). The pattern is +2. Therefore, the next letter is 10 + 2 = 12, which is L.
Analyze Third Letters
Looking at the third letters of each cluster: E(5), G(7), I(9), K(11). The pattern is +2. Therefore, the next letter is 11 + 2 = 13, which is M.
B: JKL follows a +2, +1, +1 pattern which is incorrect; C: IMN does not follow the +2 increment for any of the positions; D: KLO does not match the +2 increment pattern starting from HJK.
A is correct because each character in the sequence advances by two positions in the alphabet (B+2=D, D+2=F, F+2=H, H+2=J), resulting in JLM.
For alphabetical series, always convert letters to their numerical positions (A=1, B=2,..., Z=26) to instantly spot arithmetic progressions.
