Which is the odd one out from the following:

2, 3, 9, 19, 36, 62, 92

Your options are:

  1. 3
  2. 9
  3. 19
  4. 36

I did not create this puzzle myself. It was shared by someone in my exam preparation group on Telegram.

  • $\begingroup$ One can come up with practically any answer to questions like this. E.g. use Lagrange interpolation to construct a one-variable polynomial that takes these values except for the one you want to exclude at integers 1 through 6. To be able to provide a more helpful answer, it would be necessary to disclose the assumed background. $\endgroup$ Commented Sep 19, 2020 at 16:46

  • $\begingroup$ Yeah this is supposed to be part of logical reasoning sections. Very common in indian examinations. U can easily see these type of questions in exams for MBA like iift , nmat , snap ect.U can look for related questions for attribution on these kind of problems $\endgroup$ Commented Sep 19, 2020 at 18:47

19, because it has an even number of syllables.

NEW ANSWER

I think it is 19

Because

It is the odd one out because it contains the only digit that is not shared by the other numbers in the list: which is 1. The rule is that all the digits of every number is shared by at least one digit from another number in the list.

Unsure because there are so many other valid answers supplied, but my guess is

3

Because

It is the only number in the sequence where the sums of the factors is a perfect square.

another shot in random direction


02 = 0000010 03 = 0000011 09 = 0001001 19 = 0010011 36 = 0100100 62 = 0111110 92 = 1011100

62 is the only one with binary symmetry in the range

The series is wrong and the wrong number is 3,it should be 4

2 4 9 19 36 62 99 +2 +5 +10 +17 +26 +37

The numbers which are being added in series are getting increased by odd no. Ex 2+3 is 5 Then 5+5 is 10 Then 10+7 is 17 Then 17+9 is 26 Then 26+11 is 37

  • $\begingroup$ Beyond changing 3 to 4, you've changed the last number from 92 to 99. $\endgroup$
