- 2) series : 6,9,11,13,17,20,22,24,28,?
+3,+2,+2,+4,....
28+3=31 - 9 years agoHelpfull: Yes(22) No(1)
- 4.) 7,19,43,91,187.......
Solution : 7*2+5=19
19*2+5=43
similarly 187*2+5=379
5) 7/6,3/2,1,5/6,13/6,2,1/2.....
Solution: (7/6,5/6,1/2) (3/2,13/6) (1,2)
actually there are three series mixed together
5/6-7/6= -1/3
1/2-5/6= -1/3
now taking
13/6-3/2 =2/3
so the next term will be 13/6+2/3= 17/6
answer is 17/6
8.) -23,-16,18,14,-52,-45,37,33,-65.................
Solution : -16-(-23)= 7
14-18= -4
-45-(-52)= 7
33-31= -4
-65+7= -58
Answer is -58
- 9 years agoHelpfull: Yes(19) No(0)
- (10) Answer is 8,
0.00005*20=0.001
0.001*20=0.02
0.02*20=0.4
0.4*20=8
So answer is 8 - 9 years agoHelpfull: Yes(11) No(0)
- 3)2^11,1024,2^9,256,2^7,...
2^11,2^10,2^9,2^8,2^7............
next term... 2^6...64
- 9 years agoHelpfull: Yes(6) No(0)
- 5) 7/6, 3/2, 1, 5/6, 13/6, 2, 1/2.........
(7/6, 3/2, 1),(5/6, 13/6, 2),(1/2, ?, ?(3))
we need to find out for first question mark....
7/6 - 5/6 = 2/6-------> 5/6 - 1/2 = 2/6
3/2 - 13/6 = -2/3------>13/6 - x = -2/3--------> X = 17/6
1 - 2 = -1 ------------>2 - 3 = - 1
so, correct ans is.......... 17/6 - 9 years agoHelpfull: Yes(5) No(0)
- 14) 13,14,15,16,18,19,20,22,23,?
after 4 digits(13,14,15,16) missing 17 num... and after 3 digits(18,19,20) missing 21 num ... and after 2 digits(22,23) leave one num i.e., 24 and the ans: will be 25 . - 8 years agoHelpfull: Yes(4) No(0)
- 2) devive it into two series.. 6,11,17,22,28--> increasing like +5,+6,+5,+6
and 9,13,20,24.---->increasing like +4,+7,+4,+7
so, the ans is 24+7=31 - 7 years agoHelpfull: Yes(4) No(0)
- 6) 21
7-1=6
10-2=8
13-3=10
17-5=12
x-7=14---->x=21 - 9 years agoHelpfull: Yes(3) No(0)
- 5) (7/6,3/2,1),(5/6,13/6,2),(1/2, x,x)
7/6- (5/6)= 1/3
5/6 -1/2 = 1/3
after that, next series -> 3/2 - 13/6 = - 2/3
13/6 - x = - 2/3 => 13/6 + 2/3 = 17/6.
ans : 17/6.
