Which of the following options will replace the question mark (?) in the given series? B3, D6, F9, H12, ?
Show answer & explanation
Correct answer: A
Explanation
Given Series: B3, D6, F9, H12, ?
Analyze the letter pattern:
The letters are: B, D, F, H, ?
In the alphabet: B = 2, D = 4, F = 6, H = 8
Position increases by +2 each time: 2 → 4 → 6 → 8 → 10
The 10th letter in the alphabet is J.
Analyze the number pattern:
The numbers are: 3, 6, 9, 12, ?
Numbers increase by +3 each time: 3 → 6 → 9 → 12 → 15
Next number is 15.
So, the next term is J15.
Hence, the correct answer is option (1).
