« There are in all ten terms of proportions, established by the neo-Pythagorean School:
(c-b)/(b-a)=c/c, arithmetic proportion;
(c-b)/(b-a)=c/b, geometrical proportion;
(c-b)/(b-a)=c/a, harmonic proportion;
(b-a)/(c-b)=c/a
(b-a)/(c-b)=b/a
(b-a)/(c-b)=c/b
(c-a)/(b-a)=c/a
(c-a)/(c-b)=c/a
(c-a)/(b-a)=b/a
(c-a)/(c-b)=b/a, Fibonacci series. »
