    A)  13                         

    B)         14  

    C)  20                         

    D)         21

    Correct Answer: B

    Solution :

     Three numbers have the difference of 2, namely the first set of numbers is (1, 3, 5); second set (15, 17, 19); third set is (2, 4, 6) so the fourth set is (14, 16, 18). Hence, the missing number is 14.
