But this must follow the rule thats is: the second circle has to have radius greater than first, and third has to have radius greater than second. I know that this could be a system with multiple solutions, but is there any possibilities to have a tangent to those 3 circles? Something like a fit linear.

So what stops you from finding the lines that are tangent
to consecutive circles? Since you tell us that already KNOW
the radii for these circles, then just check to see if the lines
are collinear. If you don't know the radii of the circles,
then the problem is trivial.

What is the problem here?
