@Anirudh.

The answer to series is 3, 4, 6, 8, 12, 14, 24, 22, 48, 32...

It goes as follows 3*2=6, 6*2=12, 12*2=24. And 4+4=8, 8+6=14, 14+8=22, 22+10=32.

70 is constant for every series.

How ? perhaps correct answer is 77 ?

77 is wrong ans once think. Apply your logic to all the numbers it will not work.

70, 71, 76, __, 81, 86, 70, 91, ...

this is our question, split the question as


70,71,76

--,81,86

70,91,...

for every first column 70 will be constant
then for second column 71, 71+10, 81+10

therefore 70 is the answer.
