Read Solution (Total 12)
-
- Question posted by you is wrong. The correct question is 18,20,22,20,28,20,?
Solution: 20 is constant. so we have 18,22,28,?
The difference is 4 between 18,22 and 6 22,28.
so the next will be 28+8=36
ANS:36 - 7 years agoHelpfull: Yes(31) No(11)
- 20 cnstnt.
remaining prts r 8,22,28,?
logic-8*2 +6=22
8*3+ 4=28
8*4+ 2=34 - 6 years agoHelpfull: Yes(17) No(0)
- The logic is taking the alternate no. to form a series then we will get two series
1st is : 8,22,28,...
2nd is : 20,20.. which is constant
for first series the logic is 8,8*2+4,8*3+4,....and so on. - 7 years agoHelpfull: Yes(16) No(16)
- 8 20 22 20 28 20 ?
20 will be even places.
now 8 22 28 ?
8*3-2=22
8*4-4=28
8*5-8=32
ans will be 32. - 6 years agoHelpfull: Yes(7) No(7)
- 22-8 = 14
28-22=6
14-6=8
26-28= -2
6-(-2)=8
every time the difference is reduced by 8 so answer would be 26. - 7 years agoHelpfull: Yes(3) No(6)
- Only consider odd places of series
8,22,28,....
Now ans it can be this 8,22,28,12 - 6 years agoHelpfull: Yes(1) No(0)
- Make pairs of 2 and observe that 20 is repeating alternately.
(8,20) now add 2 in 20 (22,20) now add 8 in 20 (28,20) now add multiply of 2 and 8 i.e 16 (36,20)
Ans is 36 - 6 years agoHelpfull: Yes(1) No(0)
- answer 22:
8 , 20 , 22 , 20 , 28 ,20,
difference: (20-8)==>12
> (12-2)==>10
(22-20)==>2
>(2-2)==>0
(20-22)==>-2
>(8+2)==>10
(28-20)==>8
>(8-8)==>0
(20-28)==>-8
>(2+8)==>10
(22-20)==>2
therefore 22 hope you found the pattern - 6 years agoHelpfull: Yes(1) No(1)
- 8,20,22,20,28,20
8,22,28
here the difference increased as 4,6 and 8.
hence answer is 28+8=36 - 5 years agoHelpfull: Yes(1) No(3)
- Number other than 20 is
8,22,28
i.e. 8*2+6=22
8*3+4=28
8*4+2=34
So,34 should be the ans - 5 years agoHelpfull: Yes(1) No(0)
- 28+4=32
hguy - 7 years agoHelpfull: Yes(0) No(1)
- 8,20,22,20,28,20,42
20 is common ,remaining series is
8 ,22,28,42
