for two numbers A and B
hm= 2/((1/A) + (1/B))
for 3 numbers
hm = 3/ ((1/A)+(1/B)+(1/C))
etc.
examples
hm of (5,10) = 2/(1/5+1/10) = 2/(0.2+0.1) = 2/.3 =20/3 = 6.666..
hm of (-5, 1) = 2/(-0.2 + 1) = 2/0.8 = 2.5

H=2/(1/a+1/b) where a is the first number and b is the second number and 2 is the total numbers to average so for n numbers
H=n/(1/a1+1/a2+1/a3+...)
