• the given question is wrong
  exact question is 2,1,2,3,8,0,1,9,1,2,?
  2^1=2
  2^3=8
  8^0=1
  1^9=1
  1^2=1
  so ans is 1

• first digit is the sum of next two digits.
  eg)743=>7=4+3
  633=>6=3+3
  but 742=>7!=4+2
  so)odd one is 742

• 2^1=2
  2^3=8
  8^0=1

• 
  i think
  2+1+2+3=8
  8+0+1=9
  9+4=13

• Sorry!!
  ans is 3..
  2+1+2+3=8
  8+0+1=9
  9+1+2=13
  but the series contains only single digit.. so ans is 3

• 742 IS THE ODD ONE....because rest all numbers follow the rule that sum of digits at units and tens place is equal to the digit at the hundreds place digit

• in each case sum of all the digit is a even number
  except 742.
  sum of 742=(7+4+2)=13 (odd) [correct answer]
  sum of 743=14 (even)
  sum of 633=12 (even)
  sum of 853=16 (even)
  sum of 871=16 (even)
  sum of 990=18 (even)
  sum of 532=10 (even)

• it should be like this:
  1+2=3
  8+0+1=9
  1+2+0+1=4

• Ans is 742
  742--> 7-4=3 but it is given as 2
  743--> 7-4=3
  633--> 6-3=3
  853--> 8-5=3
  871--> 8-7=1
  990--> 9-9=0
  532--> 5-3=2
  that is subtracting 1st 2 digits gives third digit.

• 742
  evry 1st digit is the sum of 2nd and 3rd
• 8 years agoHelpfull: Yes(1) No(0)
• third digit is the difference of first two digits
  i.e. 7-4=3
  6-3=3
  8-5=3..........
  but "742" is not following this sequence, so it is odd one.

• 2,1,2,3,8,0,1,9,1,2,0,1
• 10 years agoHelpfull: Yes(0) No(3)
• last two digit add 4+2=6,4+3=7,3+3=6,5+3=8;7+1=8,9+0=9,
  3+2=5 ans.a
• 8 years agoHelpfull: Yes(0) No(0)
• first digit is the sum of next two digits
  743->7=4+3
  633->6=3+3
  742->7!=4+2...........
  so 742 is odd

• 4) 742 , as its first digit (i.e 7), is not sum of last two digits (i.e. 4 and 2) like others.
