Dividing the 5 faces of a pentagon into a ratio of 2:3
produces the Golden Section (the ratio of the length of
the dividing chord to the length of a face is 1.61818...)

2, 3, 5, 8, 13, 21, 34, ... (Fibonacci Series)

A cylinder is a
2-dimensional expansion of a circle,
and a sphere is a
3-dimensional expansion of a circle.
The ratio of proportion between a sphere and the
cylinder which encloses it is
2:3.

As The
5 Platonic Solids advance in size, they alternate
vertices to edges and faces to edges ratios of
2:3.

All larger numbers can be expressed as groupings of 2's & 3's.
