Read Solution (Total 13)
-
- 54
because there are 2 series running alternatively 2n+1,2n+2
so sixth term will be 26*2+2 = 54
and seventh term will be 15*2+1 = 31
and so on. - 13 years agoHelpfull: Yes(21) No(3)
- 3, ,7, ,15
(3*2)+1=7
(7*2)+1=15
12, ,26, ,?
(12*2)+2=26
(26*2)+2=54
The ans is:54
- 13 years agoHelpfull: Yes(13) No(0)
- 7-3=4
7+8=15
26-12=14
26+28=54 - 13 years agoHelpfull: Yes(3) No(5)
- 54
series will continue as
3,7,26,15,54,31,110,63,222,127,446,255... - 13 years agoHelpfull: Yes(2) No(2)
- 54
because there are 2 series running alternatively 2n+1,2n+2

- next number in the series is 54.
3,12,(3X2+1),(12X2+2),(7X2+1),(26X2+1)..... - 13 years agoHelpfull: Yes(1) No(0)
- look at the alternative option
3,7,15
3*2+1=7
7*2+1=15
rest alternative option are generated as
12*2+2=26
26*2+2=54

- Consider the terms in alternate manner
3
3*2+1=7
7*2+1=15
12*2+2=26
So the next term will be 26*2+2=54 - 8 years agoHelpfull: Yes(0) No(0)
