Answer / krish
answer is 729.
The logic is of two steps
1) First of all subtract the first number from second,
second from third, third from fourth and so on. You will be
left with 1, 2, 9, 18, 81....
2) The last step is divide second number by first, third by
second and so on. You will automatically find the next number.

Answer / jyothi
given series is 1,2,4,13,31,112.......
difference of 1,2=1
diff of 2,4=2
diff of 4,13=9
diff of 13,31=18
diff of 31,112=81
order is 1,2,9,18,81
1*2=2
9*2=18
81*2=162
so 112+162=274
series is 1,2,4,13,31,112,274
