**geometrically on the harmonic series, in which every value multiplied by j provides the next value, i.e.:**

**... 1/j³ : 1/j² : 1/j : 1 : j : j² : j³...
**

**(In additive progression, each value is the sum of the two preceding ones. These properties produce an arithmetical and geometrical series at the same time.)
**

**But it is also based on the additive Fibonacci number series, i.e.:
**

**1 : 1 : 2 : 3 : 5 : 8 : 13 : 21 : 34 : 55 : 89 ...
**

**in which each value is the sum of the two preceding ones, an approximation to the harmonic series, and thus tends rapidly to j, as shown by:
**

**2 - 1,5 - 1,6 - 1,625 - 1,6154 - 1,619 - 1,6176 - 1,6181 - 1,6179 > j= 1,6180339

**abased on an introduction of the human scale, whereby Le Corbusier assumes the size of a human to be 1.83 m (almost exactly 6 feet), the other important body measurements and spatial dimensions being obtained from the j series such as**

**10 - 16 - 27 - 43 - 70 - 113 - 183 - 296 (red series)
**

**20 - 33 - 53 - 86 - 140 - 226 - 366 - 592 (blue series)
