Select the option that can replace the question mark (?) in the following…

To solve this alphanumeric series, we need to analyze the pattern for the letters and the numbers separately. The series is VO39, TM35, RK31, PI27, ?.

Pattern Analysis
Letter Pattern:
Let's look at the first and second letters in each pair:

First letter: V (22) → T (20) → R (18) → P (16) → ?

Each letter shifts backward by 2 positions in the alphabet.

P (16) - 2 = 14, which corresponds to N.

Second letter: O (15) → M (13) → K (11) → I (9) → ?

Each letter also shifts backward by 2 positions.

I (9) - 2 = 7, which corresponds to G.

Number Pattern:

39 → 35 → 31 → 27 → ?

Each term decreases by 4.

27 - 4 = 23.

Combining these, we get NG23.
