WEBThe centroidal mean of two numbers a, b a, b is the number 2(a2 + ab +b2) 3(a + b). 2 ( a 2 + a b + b 2) 3 ( a + b). In a trapezoid whose bases have lengths a a and b b, it is the length of the line segment parallel to the bases which passes through the centroid. For p ∈R ∖ 0, p ∈ R ∖ 0, a generalized p p -mean of two numbers a, b a, b ...
