Q. Choose the missing terms out of the given alternatives : 
GH, JL, NQ, SW, YD, ?

Explanation by: Indresh Gehalot

Let's analyze the pattern in the given series: GH, JL, NQ, SW, YD, ?

We will examine the pattern separately for the first and second letters in each pair.

First letters:

G (7) → J (10) → N (14) → S (19) → Y (25)

The pattern follows: +3, +4, +5, +6

Next letter: Y (25) + 7 = F (6)


Second letters:

H (8) → L (12) → Q (17) → W (23) → D (4)

The pattern follows: +4, +5, +6, +7

Next letter: D (4) + 8 = L (12)


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