- Prime nos are---: 11 , 13, 17 , 19, 23 , 29, 31, 37, 41,43
Sequence Given--: 11, 8, 17, 14, 23, 24, 31, 32, ??
Sequence Formation : alternate prime num -5
ie Seq Formed as follows :
11 , 13-5, 17 , 19-5, 23 , 29-5, 31 , 37-5,41,43-5
====>that equals Given Sequence : 11,8,17,14,23,24,31,32
no next numbers will be 41,38
We need only 41 :D Thankyouuuuu.... - 10 years agoHelpfull: Yes(88) No(2)
- 11(13),17(19),23()29),31(37),41
ans is 41
39 is not prime......13*3=39 - 11 years agoHelpfull: Yes(31) No(16)
- 11,17,23,31,?
31+8=39 ans - 11 years agoHelpfull: Yes(11) No(23)
- sorry, answer should be 41 since it skips every other prime number also...
- 11 years agoHelpfull: Yes(7) No(3)
- it should be 39..
because 1 prm num is left in btwn 11,(13),17,(19)like ds.... - 11 years agoHelpfull: Yes(5) No(11)
- 11 13(8+5) 17 19(14+5) 23 29(24+5) 31 37(32+5) 41
so ans must be 41 - 11 years agoHelpfull: Yes(3) No(0)

- 10 years agoHelpfull: Yes(3) No(1)
- 11 +6 17 +6 23 +8 31 +8 39
8 14 24 32
(11-8=+3)(17-14=+3)(23-24=-1) (31-32=-1)
so ans=39 - 11 years agoHelpfull: Yes(2) No(9)
- ANS: 37
Every other number is prime 11,13,17,19,23,29,31,37
So answer is 37 - 11 years agoHelpfull: Yes(1) No(14)
- all prime no-11,(13-5),17,(19-5),23,(29-5),31,(37-5),41,(47-5)......
ans is-41 - 10 years agoHelpfull: Yes(1) No(0)
- 11-3=8+9=17,17-3=14+9=23,23+1=24+7=31,31+1=32+7=39. that is repeating the previous process
- 10 years agoHelpfull: Yes(0) No(1)
- ans:39
11,8,17,14,23,24,31,32
11-8=3
17-8=9
17-14=3
23-14=9
24-23=1
31-24=7
32-31=1
x-32=7
x=39 - 10 years agoHelpfull: Yes(0) No(4)
- all prime no-11,(13-5),17,(19-5),23,(29-5),31,(37-5),41,(47-5),
ans is-41 - 10 years agoHelpfull: Yes(0) No(1)
- There is two series
11-8=3
17-8=9
17-14=3
23-14=9
24-23=1
31-24=7
32-31=1
39-32=7
Ans-39 (Might be right) - 7 years agoHelpfull: Yes(0) No(1)
- Prime no. 2,3,5,7, 11 , 13, 17 , 19, 23 , 29, 31, 37, 41,43
11 , 13-5, 17 , 19-5, 23 , 29-5, 31 , 37-5,41,43-5
So, next numbers will be 41,38 - 6 years agoHelpfull: Yes(0) No(0)
