Sequence of numbers each formed by a specific
relationship to its predecessor. An
arithmetical progression has numbers that
increase or decrease by a common sum or
difference (for example, 2, 4, 6, 8); a
geometric progression has numbers each
bearing a fixed ratio to its predecessor (for
example, 3, 6, 12, 24); and a harmonic
progression is a sequence with numbers whose
reciprocals are in arithmetical progression,
for example 1, 1/2, 1/3, 1/4.
