rajveer singh  (10 years ago)

7..> i think answer to this question would be 119 because 17-5=12,35-17=18,65-35=30 and difference between 18-12=6,30-18=12,which means series is progressevly increasing so next term would be 24 which is added to 30 i.e 54..... which is added to 65 giving the net result of 119.

7) 119
Because 5*2 + 7 =17
17*2 + 1 = 35
35*2-5 = 65
65*2-11 = 119
Every number is multiplied by 2 and is decreased by the series of 6
9) 17
Series is +6 +2 +6 +2 added accordingly
2) 379
Every number is muliplied by 2 and the previous number in the series and 5 is added
6) 14
Every tuple is in the arithmetic of 5, 5*2,5*2-1,
3,3*2,3*2-1,
4,4*2,4*2-1,
Similarly, 7,7*2,7*2-1
