# Sequence Fractals Introduction #2

$z^2+c+s_i$ where $s_i$ is a two cycle sequence.

There are many ways to combine sequences and fractals. When I started on this adventure I made a list of several methods to investigate. $z^2+c+s_i$ probably qualifies as the simplest way to incorporate a sequence. Also a two-cycle sequence, (two repeating numbers a,b,a,b,a,b…) is perhaps the simplest non-trivial sequence.

Already with this simple setup, it is clear that we are not looking at your father’s Mandelbrot set.

I think it is obvious, but just in case. $s_i$ is the ith number in the sequence. The ith step in the fractal calculation is $z \leftarrow z^2+c+s_i$
