Question

Which is the next letter in the given alphanumeric series?
B, 25, D, 23, G, 19, K, 13, ?

• A. L
• B. P
• C. N
• D. Q

Answer 1

The Correct Option is B

Step 1: Identifying the Pattern in Letters 

The letter sequence follows:

• B, D, G, K, ?

Observing the pattern:

• B(2), D(4), G(7), K(11)

The positions of these letters in the alphabet follow:

• 2, 4, 7, 11, ?

The difference between consecutive terms is:

• +2, +3, +4

Following this pattern, the next difference should be:

• +5

11 + 5 = 16

The 16th letter of the alphabet is P.

Step 2: Identifying the Pattern in Numbers

The number sequence follows:

• 25, 23, 19, 13, ?

Observing the pattern:

• 25, 23 (−2), 19 (−4), 13 (−6)

The next difference should be:

• −8

13 − 8 = 5

Thus, the missing letter is P and the missing number is 5.

Final Answer: The correct answer is (b) P
