Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
BYE, CVG, ERI, ?, LGM
- AHMK
- BHLK
- CGMI
- DGLJ
Solution & Step-by-step Explanation
Let's break down the series position by position for each letter in the clusters:
First Letter: B, C, E, ?, L
B
+1
C
C
+2
E
E
+3
H
H
+4
L
The first letter is H.
Second Letter: Y, V, R, ?, G
Y(25)
−3
V(22)
V(22)
−4
R(18)
R(18)
−5
M(13)
M(13)
−6
G(7)
The second letter is M.
Third Letter: E, G, I, ?, M
E
+2
G
+2
I
+2
K
+2
M
The third letter is K.
Combining them gives the missing cluster: HMK.
