A.M of a and b is = a+b /2
an+1 + bn+1/ an + bn = a+b/2
2(an+1 + bn+1) = (a +b) ( an + bn)
2an+1 +2bn+1 = an+1 + abn + anb + bn+1
an+1 - anb + bn+1 - anb =0
a ( a-b ) - bn (a-b) = 0
(a-b) (an - bn) =0
a-b =0 or an- bn =0
an = bn a not equal to b
(a/b)n = 1
(a/b)n = (a/b)0
n = 0
an+1 + bn+1/ an + bn = a+b/2
2(an+1 + bn+1) = (a +b) ( an + bn)
2an+1 +2bn+1 = an+1 + abn + anb + bn+1
an+1 - anb + bn+1 - anb =0
a ( a-b ) - bn (a-b) = 0
(a-b) (an - bn) =0
a-b =0 or an- bn =0
an = bn a not equal to b
(a/b)n = 1
(a/b)n = (a/b)0
n = 0
thnx..

AM of a and b is (a+b)/2
(a+b)/2=(a^n+1 +b^n+1)/a^n +b^n
a^n+1 +a.b^n +b.a^n +b^n+1 =2a^n+1 +2b^n+1
a(a^n -b^n)=b(a^n -b^n)
(a/b)n=n^0
n=0
(a+b)/2=(a^n+1 +b^n+1)/a^n +b^n
a^n+1 +a.b^n +b.a^n +b^n+1 =2a^n+1 +2b^n+1
a(a^n -b^n)=b(a^n -b^n)
(a/b)n=n^0
n=0
