LOR
Observe the progression of the first letter: B (+9) тЖТ K (+9) тЖТ T (+9) тЖТ C (+9) тЖТ L. Each letter in the triplet also follows a +3 pattern.
Observe the progression of the first letter: B (+9) тЖТ K (+9) тЖТ T (+9) тЖТ C (+9) тЖТ L. Each letter in the triplet also follows a +3 pattern.
Analyze the first letters
B(2), K(11), T(20), C(3), ?(L=12). The gap is 11-2=9, 20-11=9, 3-20 = -17 (which is 9 mod 26), 12-3=9. Adding 9 to C(3) gives 12, which is L.
Analyze the second letters
E(5), N(14), W(23), F(6), ?(O=15). The gap is 14-5=9, 23-14=9, 6-23 = -17 (9 mod 26), 15-6=9. Adding 9 to F(6) gives 15, which is O.
Analyze the third letters
H(8), Q(17), Z(26), I(9), ?(R=18). The gap is 17-8=9, 26-17=9, 9-26 = -17 (9 mod 26), 18-9=9. Adding 9 to I(9) gives 18, which is R.
B: LNP does not follow the +9 increment pattern. C: KMO is incorrect as it starts with K. D: KNQ is the second term of the original series.
A is correct because the series follows a consistent +9 increment for every character in each triplet (B+9=K, E+9=N, H+9=Q), leading to LOR as the next term after CFI.
In alphanumeric series, always convert letters to their numerical positions (A=1, B=2...) first to reveal hidden arithmetic patterns.
