Which of the following letter-clusters will replace the question mark (?) in the given series to make it logically complete? EMU, DNT, COS, BPR,?

AAOQ

BBST

CUBO

DFCD

Answer:

A. AOQ

Read Explanation:

Series:
EMU → DNT → COS → BPR → ?

Check how each letter changes from one term to the next:

Position-wise movement

1st letter:
E → D → C → B → A (−1 each time)

2nd letter:
M → N → O → P → Q (+1 each time)

3rd letter:
U → T → S → R → Q (−1 each time)

Apply the same pattern to BPR

  • B → A

  • P → Q

  • R → Q

So the missing letter cluster is:

AQQ
