@priyanaka:

series is like that 3 22 7 45 15 91 31...

so 1st, 3rd, 5th, 7th .... no in series are computed as double of previous not +1 for example in this series 1st no is 3 so third no will be 3*2+1 =7 same way 5th no will be 7*2+1 =15

similar logic is applied to 2nd , 4th , 6th,8th,... no in series...


series is like that 3 22 7 45 15 91 31...
double of previous term +1 alternatively...

hope this helps..
