    Direction: A series is given with one/two term missing. Choose the correct alternative from the given ones that will complete the series.
    66, 36, 18?

    A) 3         

    B) 6

    C) 8                                 

    D) 9

    Correct Answer: A

    Solution :

    The pattern followed is nth term \[+\,\text{(n+1)}th\] term \[+\,(n+1)=(n\,+2)th\] term Thus, 1st term + 2nd term + 2 = 3rd term; 2nd term + 3rd term + 3 = 4 the term and so on. So, missing term = 6th term = 4th term + 5th term + 5 \[=24+41+5=70.\]
