Which letter cluster will replace the question mark (?) to complete the given series?
SYGZ, NIRT, ?, DCNH, YMYB
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ISCN.
The series follows this pattern:
1st Letter + 5 = 1st letter of next letter cluster
2nd letter + 10 = 2nd letter of next letter cluster
3rd letter + 11 = 3rd letter of next letter cluster
4th letter + 20 = 4th letter of next letter cluster
N + 5 = I, I + 10 = S, R + 11 = C, T + 20 = N
