Yes, you are right.

am i right ?
You, my friend are not right. please refer to the person above (2nd post) for the answer.
This question has never been hard to many people, it is just how long it took them to find the answer. If I didn't tell you that it was logical many might have though t it was mathematical...
the correct answer is : 31131211131221

and it does makes sense. You're describing the number above it, for example
1122321
You work it out by saying, two one (because the first is two ones) and then two two (because there's two twos) and the one three (there's only one three next).
So it ends up like this:
two one two two one three one two one one
which translantes to:
2122131211
Does it make sense now?

Before I saw the explanation in the last post, I did not understand the logic. I was trying to solve this in mathematical way, but finding no solution lol.
I have already added this question in my own forum and waiting for the reply of forum members of that site. I think, they will also enjoy this Logical Question.
Thank you for this interesting Logical Question.

(1) 1 = 1
(11) 1 + 1 = 2
(21) 2 + 1 = 3
(1211) 1 + 2 + 1 + 1 = 5
(111221) 1 + 1 + 1 + 2 + 2 + 1 = 8
It's too bad 312211 breaks the sequence (10), because this would have been pretty cool as the Fibonacci sequence. Actually, if we disallow 3's and say that 111 must be written as 2111 instead, the next sequence number would be 21112211, which adds up to 11. Still missing a few. If 22 must be written as 1212, then we come up with 2111121211, which is 13, but that's kind of pushing the envelope. After that would be 12212112111221, which is 20, which is still not enough.
Anyway, here's something to do: try to prove that if the sequence starts with 1, it is impossible for the digit 4 to appear in this sequence.
EDIT: If we say that "1111....1" must be written as 21 and then one "11" for every trailing 1, we get 1221111112111221, which is equal to 21. After that would be 1112122111111111122111121211, which is 35. It just doesn't work, for some reason.

Logical Question
13. Here is a series of comments on the ages of three persons J, R, S by themselves.
S : The difference between R's age and mine is three years.
J : are is the youngest.
R: Either I am 24 years old or J 25 or S 26.
J : All are above 24 years of age.
S : I am the eldest if and only if are is not the youngest.
R: S is elder to me.
J : I am the eldest.
R: S is not 27 years old.
S : The sum of my age and J's is two more than twice are's age.
One of the three had been telling a lie throughout whereas others had spoken the truth.
Find the age of are,S,j
