Which letter cluster will replace the question mark (?) to complete the given series?
PBXJ, TFJX, ?, BNJX, FRXJ
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. XJXJ.
Given series: PBXJ, TFJX, ?, BNJX, FRXJ
The series follows this pattern:
1. The last two letters are interchanged in the next cluster.
2. P + 4 = T; T + 4 = X; X + 4 = B; B + 4 = F
3. B +4 = F; F + 4 = J; J + 4 = N; N + 4 = R
So, the missing term in the series is XJXJ.
