Prolation Prolation Prolation is a term used in the theory of the mensural notation of medieval and Renaissance music to describe its rhythmic structure on a small scale, as opposed to "tempus", which described a larger scale. The term "prolation" is derived from the Latin "prolatio", first used by Philippe de Vitry in describing Ars Nova, a musical style that came about in 14th-century France.

Time value of money growth and true perpetual cash flow generation. Despite these qualifications, the general approach may be used in valuations of real estate, equities, and other assets. This is the well known Gordon Growth model used for stock valuation. The future value (after "n" periods) of an annuity (FVA) formula has four variables, each of which can be solved for by numerical methods: To get the FV of an annuity due, multiply the above equation by (1 + i). The future value (after "n" periods) of a growing annuity (FVA) formula has five variables, each of which can be solved for by
