```							Dear Anvita  Dear student,a, b , c  are in H.P   we know  that  b =  2ac /  a+ c  now  we have to prove that  a/ b+ c ,  b / c+ a , c / a + b are in h.p  i .e  we  have  to prove that  b = 2ac / a+ c ---1     substitute value of  a+ c  from  --1  in above equation      hence proved  these  are in h.p

```							Another method : It is given that a,b,c are in H.P.By definition, 1/a , 1/b , 1/c are in A.P.Multiply each term by a+b+c(a+b+c)/a , (a+b+c)/b , (a+b+c)/c  are also in A.P.i.e. 1 + (b+c)/a , 1 + (c+a)/b , 1 + (a+b)/c  are in A.P.Subtracting 1 from each term, we get(b+c)/a , (c+a)/b , (a+b)/c  are in A.P. Their reciprocals a/(b+c), b/(c+a), c/(a+b) are in H.P.
