A series is formed in the following manner
A(1)=1
A(n)=f(m) numbers of f(m)followed by f(m) numbers of 0;
m is the number of digits in A(n-1)
Find A(30). Here f(m) is the remainder when m is divided by 9
I can't solve this.Plz help.

It's your first post, and so welcome! But it seems you haven't checked out the posting rules yet.
Posted in wrong forum, topic moved.
Posted twice, so duplicate post removed.
And the problem and answer are already in a post in the forum

Please check the posting rules to make sure that they don't occur again.
