Hello guys

How do I find the n'th term of the series give below

1,11,21,31,111,211,311,121,221,321.....

It goes like this
You take the first term. Append 1,2 and 3 successively. take the second term and do the same thing and go on and on.

One of my customers wants to assign Registration Numbers for his clients in this fashion. So I have to generate the next code in VB

Thanks for any help.
