    Select the term from among the given options that can

    replace the question mark (?) in the following series. 2A, 3C, 5F, 7J, 11O, ?
    A 13U Correct Answer Incorrect Answer
    B 15U Correct Answer Incorrect Answer
    C 17U Correct Answer Incorrect Answer
    D 13V Correct Answer Incorrect Answer

    Solution

    2A, 3C, 5F, 7J, 11O The first number in each pair is a prime number (2, 3, 5, 7, 11), and the second letter seems to be alphabetically ordered (A, C, F, J, O). If we continue this pattern, the next prime number after 11 is 13, and the next letter in the alphabet after O is U. So, the next term in the series should be 13U. Therefore, the correct option is: 13U
