IAS EXAM PUZZLE SOLUTION

SOLUTION OF THIS PUZZLE

Check the series carefully and you will be able to solve this one.

To get the 2nd number in the series we have to multiply by 2

So 6 x 2 = 12

To get next no. it is;

12 x 4 = 48;

To get next no.;

48 x 2 = 96

next no. will be;

96 x 5 = 480

Since every alternate number is x 2 to get the next number we will have to multiply the no. with 2

So to find ?;

480 x 2 = 960

Hence answer is 960
