Mean

Chambers's Encyclopaedia, Volume 7: Maltebrun to Pearson, p. 107–108

Mean, in Mathematics, is a term interpolated between two terms of a series, and consequently intermediate in magnitude. The Geometrical Mean (q.v.) of two numbers is always less than their Arithmetical Mean (q.v.) and greater than their Harmonic Mean, and the geometric mean is itself a geometric mean between the two others.
