Answer:
90° CCW
Step-by-step explanation:
The angle from C to the origin to C' is a right angle when measured counterclockwise (in the usual direction).
ΔA'B'C' is a rotation of ΔABC 90° CCW.
__
This is fully equivalent to a rotation of 270° CW.
In order to have a linear equation, you have to write an equation like
The sequence has to start with 3, so we must choose 
, because this guarantees that when 
we have
Now, 
must be even. In fact, if is even, 
will always be even for every possible 
, and 
will be odd.
So, for example, you might choose
Which will produce the following sequence:
and so on
