Select the letter that can replace the question mark (?) in the following series.
A, E, I, ?, Q, U
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → M
The letters are compared by their positions in the alphabet; here each letter is 4 places after the one before it.
A (1), E (5), I (9): 4 places apart
The missing letter is \(9+4=13\)th, that is M
Then \(13+4=17\) is Q and \(17+4=21\) is U, as in the series
