Geometric rate

A geometric rate of growth occurs when a series increases in proportion to its current value, as in doubling per century in the case of Best New Conservative Words. Symbolically, this could be written as

<math>Conservative Words Today = Original Conservative Words\times 2^{\frac{time}{100 years}}</math>

where <math>time</math> is the amount of time since the <math>Original Conservative Words</math> were counted (perhaps the year 1600 as described in the above article).
