    Which sequence of letters when placed at the blanks one after another will complete the given letter series? \[b\_b\_\,bb\_bbb\_bb\_b\]

    A)  bbbbba                        

    B)  bbaabb            

    C)  ababab             

    D)         aabaab            

    Correct Answer: C

    Solution :

    The series is \[b\underline{a}b\underline{b}/bb\underline{ab}/bbb\underline{a}/bb\underline{b}b.\] Thus, in each sequence, 'a' moves one step forward and 'b' takes its place and finally in the fourth sequence, it is eliminated.
