- 14
(2 , 5 , 9) , ( 1 , 5 , 10) , (3 , 8 , x )
first bracket => 2 , 2 + 3 , 2 + ( 3 + 4)
Second bracket => 1 , 1 + 4 , 1 + (4 + 5)
third bracket. => 3 , 3 + 5 , 3 + (5 + 6)
=> x = 3 + (5 + 6) = 14 - 11 years agoHelpfull: Yes(59) No(6)
- 14 is the next sequence because (2,5,9)(1,5,10) and (3,8,?)
in these groups the differences in no. are (3,4) (4,5) so in last group it'll be (5,6) so 14 is next number............ - 11 years agoHelpfull: Yes(26) No(2)
- ans is 5
(2,5,9) (1,5,10) (3,8,x)
2+5+9=16
1+5+10=16
3+8+x=16
=>x=16-(3+8)=5 - 11 years agoHelpfull: Yes(16) No(17)
- 2+(3)=5
5+(4)=9
1+(4)=5
5+(5)=10
3+(5)=8)
8+(6)=14 - 11 years agoHelpfull: Yes(7) No(1)
- 14there is +3 ,+4 den-8 again +4,+5,din-7..so d last term is 14

- 14
the series is like 2,5,9,1,5,10,3,8
just c the differences. 3,4,-8,4,5,-7,5 so the next difference shd be 6. 8+6=14.
so the answer is 14 :) - 11 years agoHelpfull: Yes(1) No(0)
- ans may be 17
2+5=7,
7+2=9 make the 3rd term,
1+5=6,
6+4=10, make the 6th term,
3+8=11,
11+6=17,make the 9th term - 11 years agoHelpfull: Yes(1) No(4)
- (2,5,9),(1,5,10),(3,8,?)
2+5+9=16
1+5+10=16
3+8+?=16 => ?=5
Ans=5 - 11 years agoHelpfull: Yes(1) No(1)
- 2+3=5
5+4=9
9-8=1
1+4=5
5+5=10
10-7=3

- 14
2 1 3
5 5 8
9 10 14
2+3 = 5 1+4= 5 3+5= 8
5+4= 9 5+5 = 10 8+6 = 14 - 11 years agoHelpfull: Yes(0) No(0)
- (2 + 5 + 9) = 16
(1 + 5 + 10) = 16
(3 + 8 + ? ) = 16
? = 5;
now i know the answer is 14
but i thought like this way...:) - 7 years agoHelpfull: Yes(0) No(0)
