Find the missing term in the series:

B12D, G32I, L52N, ?, V92X

Q72S

The correct answer is Option (1) → Q72S

1. The First Letter

Let's look at the sequence of the first letters: B, G, L, ?, V.

We can track their positions in the alphabet:

• B = 2
• G = 7 ($+5$)
• L = 12 ($+5$)
• ? = $12 + 5 = 17 \rightarrow$ Q
• V = $17 + 5 = 22$ (Matches the sequence)

2. The Middle Number

Let's look at the sequence of numbers: 12, 32, 52, ?, 92.

The pattern here is a simple addition of 20:

• $12 + 20 = 32$
• $32 + 20 = 52$
• $52 + 20 =$ 72
• $72 + 20 = 92$ (Matches the sequence)

3. The Last Letter

Finally, let's look at the last letters: D, I, N, ?, X.

Tracking their positions in the alphabet:

• D = 4
• I = 9 ($+5$)
• N = 14 ($+5$)
• ? = $14 + 5 = 19 \rightarrow$ S
• X = $19 + 5 = 24$ (Matches the sequence)

Final Result

Combining these three parts (Q, 72, and S), we get: Q72S

The correct option is Q72S.
