Question

Select the letter-cluster from among the given options that can replace the question mark (?) in the following series: HDZ LGB PJD TMF ?

• A. XPH
• B. XOH
• C. XPG
• D. WPH

Answer 1

Answer:

A. XPH

Let's observe the pattern:

HDZ → LGB → PJD → TMF → ?

Look at each position separately.

Term	1st	2nd	3rd
HDZ	H	D	Z
LGB	L	G	B
PJD	P	J	D
TMF	T	M	F

1st letters

H → L → P → T

Each increases by +4.

So next is:
T → X

2nd letters

D → G → J → M

Each increases by +3.

So next is:
M → P

3rd letters

Z → B → D → F

This moves forward by +2 each time (wrapping after Z):

• Z → B

• B → D

• D → F

• F → H

So the next letter is H.

Final answer:

XPH
