    Choose the correct option to complete the series.

    A) 17                      

    B)        14

    C) 15                                

    D) 12

    E) None of these

    Correct Answer: D

    Solution :

    Explanation: Option (d) is correct because in the given series numbers and letters take place alternately. Every next number decreases by 1, 2, 3 and 4 respectively. Let us see: \[22-1\text{ }=\text{ }21\] \[21-2\text{ }=\text{ }19\] \[19-3\text{ }=\text{ }16\] \[16-4\text{ }=\text{ }12.\] If you see the letters, you find that every next letter is one letter backward from the previous letter. Rest of the options is incorrect because of the correctness of option (d).
