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

$ConservativeWordsToday=OriginalConservativeWords\times 2^{\frac {time}{100years}}$

where $time$ is the amount of time since the $OriginalConservativeWords$ were counted (perhaps the year 1600 as described in the above article).
