12232334233445
in each iteration, it repeats the last added numbers, and add the next two number sequence, so it's 445.
(the next iteration would be
1223233423344523344556
)
Marques...thanks for your comment...your answer is correct
But I was expecting a different answer
The pattern is - the number of 1's in the binary expansion of the positive integers starting from 1.
#Number #Binary Equivalent #No: of 1's
1 , 1 , 1
2 , 10 , 1
3 , 11 , 2
4 , 100 , 1
5 , 101 , 2
6 , 110 , 2
7 , 111 , 3
8 , 1000 , 1
...........
..........
etc
The next three numbers in the series are 4, 3, 4.
5,1,2
