The answer is 35.35
If you wrote the numbers down correctly, then the solution is simply to add each number to itself, only you reverse the numbers on each side of the decimal. For example: 4.7 + 7.4 = 12.1
This would mean the sequence would go like this: 4.7 12.1 13.22 35.35 (which is 13.22 + 22.13).
You're welcome B)

Nice ... !
The greatest challenge to any thinker is stating the problem in a way that will allow a solution.

It does seem that, in fact, you reverse the numbers for each side of the decimal. So, it would not be 35.35, rather 35.53.

<_< I believe the next two numbers would be 22.13 and 31.04. Some one message me and let me know if i'm right or wrong and if I'm wrong let me know the correct answers. Thanks!

4.7 12.1 13.22...
4.7+7.4=12.1
12.1+1.12=13.22
13.22+22.13=35.35
4.7+7.4=12.1
12.1+1.12=13.22
13.22+22.13=35.35

22.13 is what you add to 13.22 to get the next number

If you reverse the numbers either side of the decimal then you would end up with 12.1 + 21.1 = 33.2 NOT 13.22
