Every term of the series after the first is the harmonic mean of the neighboring terms; the phrase harmonic mean likewise derives from music. 调和序列中,第一项之后的每一项都是相邻两项的调和平均数;而“调和平均数”一词同样地也是源自音乐。 LASER-wikipedia2 The index is based on the genera...

If a ,b ,c are first three terms of a G.P. If the harmonic mean of a and b is 20 and arithmetic mean of b & c is 5, then (A)no term of this G.P. is sq
Since $\sum_{n=1}^{\infty}b_n$ is divergent (and definitely not convergent), we can say that the harmonic series, $\sum_{n=1}^{\infty}a_n$, is also divergent. Why don’t we apply everything that we learned so far – from finding the terms of a harmonic series, finding the...
The harmonic mean is the weighted harmonic mean when the weights are equal to 1. The weighted harmonic mean of x1, x2, x3 with the corresponding weights w1, w2, w3 is given as: ∑i=1nwi∑i=1nwixi\displaystyle{\frac{\sum^n_{i=1}w_i}{\sum^n_{i=1}\frac{w_i}{x_i}}}∑i...
