Question

Find the missing letters ......., PSV, EHK, TWZ, ILO
A) BEH
B) ADG
C) ZCF
D) IMP

Answer 1

Hint: Observe the given pattern and fill the blank. Write all the alphabets once, find the difference and the common pattern followed.

Complete step by step answer:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.
First, take – PSV
So, After P, S comes after skipping two alphabets.
      After S, V comes after skipping two alphabets.

Similarly, observe – EHK
Here, After E, H comes after skipping two alphabets
           After H, K comes after skipping two alphabets
Also, EHK pair is found going back eleven alphabets.

Now, take TWZ
Here, After T, W comes after skipping two alphabets
           After W, Z comes after skipping two alphabets
Also, TWZ pair is found moving to the fifteenth alphabet

Similarly, observe - ILO
Here, After I, L comes after skipping two alphabets
           After L, O comes after skipping two alphabets
Also, ILO pair can be found going back eleven alphabets

Now, as per the observation sequence follows –
$.......,{\text{ + 15, ( - 11), + 15, ( - 11)}}$

So, first would be pair which can be found moving back to the eleventh position.

Now, check the given multiple options

Option A- BEH
After B, E comes after skipping two alphabets and H comes after skipping two alphabets. B is on the tenth position.So, it does not follow the given pattern.

Option B- ADG
After A, D comes after skipping two alphabets and H comes after skipping two alphabets.
So, it follows the given pattern and is on the eleventh position.

Option C- ZCF
It does not follow the pattern of moving back to eleventh positions.

Option D –IMP
It does not follow the pattern of moving back to eleventh positions.

Hence, from the given multiple choices, option B is the correct answer.

Note:
These types of questions follow some of the other common patterns, observe it, and double-check the difference.
