Which of the following letter-clusters will replace the question mark (?) in the given series?
BINZ, EJOY, HKPX, ?, NMRV
- AKLRW
- BKLQW
- CJLQW
- DJLRW
Solution & Step-by-step Explanation
Let's analyze the positional shift of each letter in the successive letter-clusters:
1st letter pattern:
B
+3
E
+3
H
+3
K
+3
N
2nd letter pattern:
I
+1
J
+1
K
+1
L
+1
M
3rd letter pattern:
N
+1
O
+1
P
+1
Q
+2
R (Notice: N(14)→O(15)→P(16)→Q(17)→R(18), so it is a +1 increment throughout).
4th letter pattern:
Z
−1
Y
−1
X
−1
W
−1
V
Combining the missing positions: K, L, Q, W.
Therefore, the required cluster is KLQW.
