Complete the series: B2D, E5G, H8J, ?
K11M
J11L
K12M
L11N
K11M
Observe the first and last letters increment by +3 positions (A=1, B=2...) while the middle digit increments by +3.
Observe the first and last letters increment by +3 positions (A=1, B=2...) while the middle digit increments by +3.
Analyze the first letter pattern
Starting letters: B(2), E(5), H(8). The gap is +3 for each step (2+3=5, 5+3=8). Following this, 8+3=11, which corresponds to the letter K.
Analyze the number pattern
Middle numbers: 2, 5, 8. Each number increases by +3 (2+3=5, 5+3=8). Following this, 8+3=11.
Analyze the last letter pattern
Ending letters: D(4), G(7), J(10). The gap is +3 for each step (4+3=7, 7+3=10). Following this, 10+3=13, which corresponds to the letter M.
B: J11L is incorrect as J is at 10 and L is at 12, failing the +3 increment rule. C: K12M is incorrect because the middle number must be 11, not 12. D: L11N is incorrect because the sequence starts with K, not L.
A is correct because the series follows a consistent +3 increment for the first letter, middle number, and last letter, resulting in K11M.
For alphanumeric series, always break the term into individual components and solve each sequence separately to avoid missing complex multi-part patterns.
