  Draw Sizer - Geometric Progression
With geometric progression, drawer heights increase by a constant multiplicative factor such that the ratio of consecutive drawer heights is the same.
A geometric progression of drawer heights may be quite similar to an arithmetic progression depending on the choice of sizing parameters.
For example, this technique could be used to proportion the spacing of stretchers in a table, the stepped front of a sideboard, the arrangement of decorative molding on a chest or armoire, or even the arrangement of patterns in a segmented wood turning.

progression, in mathematics, sequence of quantities, called terms, in which the relationship between consecutive terms is the same.
An arithmetic series is the indicated sum of an arithmetic progression, and its sum of the first n terms is given by the formula [2a+(n-1)d]n/2; in the above example the arithmetic series is 3+7+11+15+…, and the sum of the first 5 terms, i.e., when n=5, is [2•3+(5-1)4] 5/2=55.
A harmonic progression is one in which the terms are the reciprocals of the terms of an arithmetic progression; it therefore has the general form 1/a, 1/(a + d), …, 1/[a+(n-1)d].

With a geometric progression, the spacing of the grid is increased by multiplication and not addition.
Geometric progressions have one drawback, however, as the size of the grid may become very large - even if the common ratio is quite small.
Rather than use the geometrical progression to define the measure for the spacing, we can also use the geometrical progression to define the grid using the Cartesian grid directly.

However, if desired, the idea of the mean can be extended beyond its original sense of a particular type of middle place or term to comprise a progression for the purposes of enlarging or reducing elements in an orderly mathematical fashion, and especially for purposes of visual perspective, the diminution of forms in pictorial space.
Applying a mean to determine a progression is quite simple in the case of the arithmetic and geometric means, but in the case of the harmonic mean, it is not nearly as straightforward.

One of the greatest deterrents to the practice of safer sex among teens and young adults is the mindset, "It can't happen to me." This lesson dramatizes the rapid geometric progression possible in the spread of HIV and helps students understand how exposure to possible infection or avoidance of infection is within their control.
Students will become aware of the geometric patterns of infection in epidemics and see how rapidly HIV, as well as other sexually transmitted diseases (STDs), can be spread through unprotected intercourse.
They will have the opportunity to imagine what it feels like to learn that they have been infected with an incurable, fatal disease, or to imagine what it feels like to learn that they have avoided infection by practicing safer sex.
