Which letter cluster will replace the question mark (?) to complete the given series?
ZDFA, CIMJ, ?, ISAB, LXHK
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. FNTS.
Given series: ZDFA, CIMJ, ?, ISAB, LXHK
The series follows this pattern:
ZDFA, CIMJ
Z + 3 = C
D + 5 = I
F + 7 = M
A + 9 = J
Similarly;
CIMJ,?
C + 3 = F
I + 5 = N
M + 7 = T
J + 9 = S
So, the missing term in the series is FNTS.
