This is not a homework question, just studying previous exams for my upcoming final. My professor said it would be easier if you could see the patterns taking form if you expand the equations up to a few steps. The sequence \(c\) was defined by \(c_r\) = the number of strings of zeros and ones with length \(r\) having no consecutive zeros (example 8.2.1(c)).
