6.       A   Numbers are all primes. The next prime is 43
7.       A Numbers are alternatively multiplied by 3 and divided by 2.
        So, the next number = 54 ÷ 2 = 27.
8.       C The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.
        So, the next number is 8 x 9 = 72.
9.       B Each number is the proceeding number multiplied by -2.
        So, the required number is -128.
10.   B  Numbers are (2^3 - 1), (3^3  - 1), (4^3  - 1), (5^3  - 1), (6^3  - 1), (7^3  - 1) etc.
         So, the next number is (8^3  - 1) = (512 - 1) = 511.
