According to the fractal law shown in Figure A, the fractal of 1 white circle is two white circles, and the fractal of 1 black circle is 1 white circle and two black circles.

The first line is (1, 0), the second line is (2, 1), the third line is (5, 4), and the number of white cycles in the fourth line is 2× 5+4 =14; The number of black circles is 5+2×4= 13,

∴ The coordinate in the fourth line is (14,13);

The coordinate of the fifth line is (4 1, 40).

The number of white circles in each row multiplied by 2 is 2, 4, 10, 28, 82, namely 1+ 1, 3+ 1, 9+ 1, 27+ 1, 86544.

∴ The number of white circles in the nth row is 3n? 1+ 12, and the number of black circles is 3n? 1+ 13? 1=3n？ 1? 13,

So the answer is (14, 13), (3n? 1+ 12，3n？ 1? 12)n∈N+。
