1) First of all subtract the first number from second,
second from third, third from fourth and so on. You will be

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
