Question : Directions: Select the letter-cluster that can replace the question mark (?) in the given letter-cluster series.
AGM, EKN, IOO, ?, UWQ
Option 1: MSP
Option 2: OSP
Option 3: OTP
Option 4: NSQ
Correct Answer: OSP
Solution :
Given:
AGM, EKN, IOO, ?, UWQ;
The alphabetical order of the vowels is –
A, E, I, O, U
Add 4 and 1 in the second and third letter respectively and write the immediate next letter for vowels –
AGM → A + 1 = E (Immediate next letter of A is E), G + 4 = K, M + 1 = N → EKN
EKN → E + 1 = I (Immediate next letter of E is I), K + 4 = O, N + 1 = O → IOO
IOO → I + 1 = O (Immediate next letter of I is O), O + 4 = S, O + 1 = P → OSP
OSP → O + 1 = U (Immediate next letter of O is U), S + 4 = W, P + 1 = Q → UWQ
So, the required missing term in the series is OSP. Hence, the second option is correct.
