Observe the first letters of each cluster; they form a +4 increment sequence. Apply the same +4 increment to the middle and last letters of the previous cluster to find the next.
Observe the first letters of each cluster; they form a +4 increment sequence. Apply the same +4 increment to the middle and last letters of the previous cluster to find the next.
Analyze the first letters of each cluster
L(12), P(16), T(20), X(24), B(2/28). The pattern is +4 for each step: 12+4=16(P), 16+4=20(T), 20+4=24(X), 24+4=28(B), 28+4=32(F). The first letter is F.
Analyze the second letters of each cluster
O(15), S(19), W(23), A(1/27), E(5/31). The pattern is +4 for each step: 15+4=19(S), 19+4=23(W), 23+4=27(A), 27+4=31(E), 31+4=35(I). The second letter is I.
Analyze the third letters of each cluster
R(18), V(22), Z(26), D(4/30), H(8/34). The pattern is +4 for each step: 18+4=22(V), 22+4=26(Z), 26+4=30(D), 30+4=34(H), 34+4=38(L). The third letter is L.
A: FJM is wrong because the third letter follows a +4 increment resulting in L, not M. C: GKL is wrong because the first and second letters do not follow the +4 sequence. D: EIM is wrong because the first letter must be F based on the B+4 calculation.
B is correct because the series follows a consistent +4 increment for each of the three positions in the cluster, leading to F, I, and L.
For alphabet series, always convert letters to their numerical positions (A=1, Z=26) to simplify arithmetic operations like addition and subtraction.
