Question

Select the letter-cluster from among the given options that can replace the question mark (?) to complete the given series:  
BVTO, DTVM, ?, HPZI, JNBG.

Accepted Answer

Let's analyze the given series: BVTO, DTVM, ?, HPZI, JNBG.

Let's write the positions of each letter in the alphabet:
B=2, V=22, T=20, O=15
D=4, T=20, V=22, M=13
?=?
H=8, P=16, Z=26, I=9
J=10, N=14, B=2, G=7

Let's look for a pattern column-wise:

First letters: B, D, ?, H, J
Positions: 2, 4, ?, 8, 10
Pattern: +2 each time (2→4→6→8→10)
So, the missing letter is position 6 = F.

Second letters: V, T, ?, P, N
Positions: 22, 20, ?, 16, 14
Pattern: -2 each time (22→20→18→16→14)
So, the missing letter is position 18 = R.

Third letters: T, V, ?, Z, B
Positions: 20, 22, ?, 26, 2
From 20→22→24→26→2 (after Z, it wraps to A=1, B=2)
So, the missing letter is position 24 = X.

Fourth letters: O, M, ?, I, G
Positions: 15, 13, ?, 9, 7
Pattern: -2 each time (15→13→11→9→7)
So, the missing letter is position 11 = K.

So, the missing cluster is F R X K.

Among the options, option 4 is FRXK.

Therefore, the answer is option 4.
