Given that AM's are inserted between two sets of numbers a,2b and 2a,b where a,b E R suppose further that the mean between these sets of numbers is same then the ratio a: b =1) 1:n2) n: 13) n +1:14) n +2:n-1​

Answer»

Step-by-step explanation:a...n A.M.s........2B d= n+1 2b−a ​A  m ​ =a+m(  n+1 2b−a  )...(1) 2a.........n A.M's ...........b d=  n+1 b−2a ​A  m =2a+m(  n+1 b−2a  )...(2) equating (1) and (2) a=  n+1 m (b+a)⇒  b a  =  n−m+1 m ​
