Correct Answer: K 58 Q
Solution : Given:
C 2 E, E 5 H, G 12 K, I 27 N,?
The given series follows the following pattern:
C 2 E → E 5 H ⇒ C + 2 = E ; 2 × 2 + 1 = 5 ; E + 3 = H
E 5 H → G 12 K ⇒ E + 2 = G ; 5 × 2 + 2 = 12 ; H + 3 = K
G 12 K → I 27 N ⇒ G + 2 = I ; 12 × 2 + 3 = 27 ; K + 3 = N
Similarly, I + 2 = K ; 27 × 2 + 4 = 58 ; N + 3 = Q
Therefore, the next letter cluster in the series is K 58 Q
Hence, the third option is correct.
