Which of the following terms will replace the question mark (?) in the given series?
MBZT, KYBW, IVDZ, ?, EPHF
- AGRFB
- BFSGC
- CGSFC
- DFRGB
Solution & Step-by-step Explanation
Let's track the position shift for each corresponding letter in the series:
1st letter: M(13)
−2
K(11)
−2
I(9)
−2
G(7)
−2
E(5)
2nd letter: B(2)
+3
Y(25) ? Let's check alternative pattern: B(2)
−3
Y(25)
−3
V(22)
−3
S(19)
−3
P(16) ... wait, let's verify with the next cluster: MBZT,KYBW,IVDZ.
The second letters are: B→Y→V→?→P.
Let's look at the sequence: 2→25 (which is 2−3=−1≡25) →22 (which is 25−3=22) →19=S→16=P. So the second letter is S.
3rd letter: Z(26)
+2
B(2)
+2
D(4)
+2
F(6)
+2
H(8)
4th letter: T(20)
+3
W(23)
+3
Z(26)
+3
C(3)
+3
F(6)
Combining the letters found for the missing term: G, S, F, C.
Therefore, the correct term is GSFC.

The second letters are: B→Y→V→?→P.
Let's look at the sequence: 2→25 (which is 2−3=−1≡25) →22 (which is 25−3=22) →19=S→16=P. So the second letter is S.

Combining the letters found for the missing term: G, S, F, C.
Therefore, the correct term is GSFC.
