3 GEOMETRIC The limit to what can he done using geometry is the mathematical knowledge and imagination of the individual. As an example let us consider Le Corbusier's Modulor shown in figure. Modulor is (based upon the Fibonacci series, examples of which arc 1,1,2,3, 5, 8, 13, 21, 34..…. 1.3.4.7. 11. 18. 29. 47... In both cases each term is the sum of the two preceding terms. Thus if xn is the nth term. Xn = Xn-1 + Xn-2 This equation has the general solution Xn= (v< p 2-1) < p n + (v
