Find out the next two numbers in the series.
359,  4713,  61121, 91733, _ , _ ,...........

Answer

3  5  9     ====> 3    3*2 -1  =5      5*2 -1 =9

4 7 13     ====>4     4*2 -1  =7      7*2 -1  =13

6 11 21       =====> 6     6*2 -1   =11    11*2 -1 =21

9  17 33  ====> 9    9*2 -1    =17   17*2 -1  =33

3 ,       4 ,      6 ,    9 ,...................... Next two numbers   9+4 =13    13 +5 =18

    +1     +2       +3

Next two numbers in the series

13  13*2 -1    25*2-1  ==> 132549

18  18*2 -1    35*2-1  ==> 183569

359,  4713,  61121, 91733, 132549 , 183569 ,...........
