In the following question, various terms of a letter series are given with one term missing as shown by (?). Choose the missing term out of the given alternatives.

$\text{ABP, CDQ, EFR, }(\dots?\dots)$

A) GHS

the first sequence is ABP --> CDQ --> EFR --> the next could be clearly starting with GH

as first sequence is starting with AB

2nd sequence is starting with CD

3rd sequence is starting with EF

So, the next sequence could be starting with GH.

Now, in the first sequence after AB is P

in the 2nd one after CD is Q

in the 3rd one after EF is R

So, the 4th one must be GH S.

The patterns of the latter series are as follow:

option A GHS is correct.
