Correct Answer - Option 4 : U11V
The given series: A2B, E3F, I5J, O7P, ?
The first letter of each term is a vowel, the third letter of each term is the successor of the first letter of the term as per the English alphabetical series. The middle letter of each term is the prime number.
Vowels in the sequence: A, E, I, O, U
Prime numbers in the increasing order: 2, 3, 5, 7, 11
Thus, the next term will start with U followed by the number 11. The last letter of the term will be the successor of U i.e. V.
Hence, the next term is U11V.
