AZ , CX , FU , ?

Explanation by: Indresh Gehalot

Let's analyze the pattern in the given series: AZ, CX, FU, ?

First letters:

A (1) → C (3) → F (6) → ?

The pattern follows: +2, +3, +4

Next letter: F (6) + 5 = K (11)


Second letters:

Z (26) → X (24) → U (21) → ?

The pattern follows: -2, -3, -4

Next letter: U (21) - 5 = P (16)


Thus, the missing term is KP, and the correct answer is:
(D) KP
