Arithmetic, Geometric, and Harmonic Means
In other words, if A, G, and H are the arithmetic, geometric, and harmonic means, respectively, then H ≤ G ≤ A.
For a1 ≥ a2 ≥ ... ≥ an and b1 ≥ b2 ≥ ... ≥ bn,
For positive ak, bk and p > 1,
For x > -1, x ≠ 0, and integers n > 1,
A special case is
For 0 < p ≤ q and positive ak,

For 0 < p < q,
Let f be a continuous strictly increasing real-valued function on [0, ∞), with f(0) = 0 and as x approaches ∞, f(x) approaches ∞. Then if g is the inverse function of f, for any positive numbers a, b we have

It may be much better when equal conditions are given too.
