Question

if h1,h2 are the harmonic means between a,b then h1+h2/h1h2=​

Answer 1

Answer:

d=(1/b-1/a)/n+1=(1/3-1/2)/20+1=-1/126

1/H1=1/a+d=1/2-1/126=62/126

H1=126/62

1/H20=1/a+20*d=1/2+20*(-1/126)=43/126

H20=126/43

now,H1+2/H1-2=(126/62+2)/(126/62-2)=125

H20+3/H20-3=(126/43+3)/(126/43-3)=-85

finally,125+(-85)=40 ans
