-
- The ans is 1
check the alternating series
3,1,5,1,6,1 - 12 years agoHelpfull: Yes(41) No(33)
- 5) 3,2,1,4,5,4,1,0,6,3
Take the first three numbers
3 - 2 = 1
1 + 2 = 3
Leave the next number
Take the next three numbers
5 - 4 = 1
1 + 4 = 5
Leave the next number
Take the next three numbers
6 - 3 = 3
3 + 3 = 6
So the answer is 3. :)

- 3,2,1,4,5,4,1,0,6,3
diff(3,2)=-1
diff(4,5)=1
diff(1,0)=-1
diff(3,x)=1 so x=4 - 11 years agoHelpfull: Yes(17) No(7)
- 3+2+1+4=10
5+4+1+0=10
6+3+1+0=10
taking 4 numbers as a pair and the 3rd number is 1 that is common in all the sequences - 8 years agoHelpfull: Yes(12) No(1)

- 3-2 = 1 and next dummy number
4-5 = -1 ,,
1-0 = 1 ,,
3-x = -1 so x=3+1--->4 - 10 years agoHelpfull: Yes(3) No(3)
- Ans: 8
3+2=5-1=4
5-4=1-1=0
6+3=9-1=8 - 10 years agoHelpfull: Yes(2) No(1)
- at even places,
2+2=4,4
then
4+2=6,6 - 12 years agoHelpfull: Yes(1) No(13)
- correct ans is 3

- 3,2,1,4 take 2 mid get first 2+1=3
5,4,1,0 ''''' '' ''' 4+1=5
6,3,x,y' ' ' ' '' '' ' ' ' ' ' ' ' ' 3+x=6
so x=6 (ANS) - 8 years agoHelpfull: Yes(1) No(1)

- This series has following pattern:
(3, 2, 1), (4, 5, 4), (5, 1, 0), (6, 3, ?).
Here obviously the missing digit is 2.
Logic: The first digit in every parenthesis (3, 4, 5, 6) are increasing by 1. The second digit in parenthesis are (2, 5, 1, 3). Here every digit is one more than two times of preceding digit - Only unit place digit is taken. For example, (2*2+1 = 5), (5*2+1 = 11, so 1 is taken), (1*2+1 = 3). Last digit in every parenthesis is one less than the second digit. - 7 years agoHelpfull: Yes(1) No(0)
- there are set of 3 nos.
(3,2,1)
(4,5,4)
(5,1,0)
(6,3,2)
so next series starts from 7.
this ques is repeating i saw this ans before
is this ans crt?? - 8 years agoHelpfull: Yes(0) No(2)
- STEPS 2 SOLVE-
1>3-2=+1 LEAVE THE NEXT DIGIT I.E 1
2>4-5=-1 LEAVE THE NEXT DIGIT I.E 4
3>1-0=+1 LEAVE THE NEXT DIGIT I.E 6
4>3-4=-1 so the ans would be 4 - 7 years agoHelpfull: Yes(0) No(0)
- 3,2,1, ignore 4, 5,4,1, ignore 0, 6,3,?
3-2=1,ignore 4, 5-4=1, ignore 0, 6-3=3
Ans=3 - 7 years agoHelpfull: Yes(0) No(0)
