In just intonation, 161/128, the arithmetic mean major third is the frequency ratio between the 161th and the 128th harmonic. It is the arithmetic mean between the just major third and the Pythagorean major third: (5/4 + 81/64)/2 = 161/128.
It can also be calculated from the syntonic comma: ((81/80 - 1)/2 + 1)⋅(5/4) = 161/128.
