let Tr be the rth term of an AP whose first term is a abd common difference is d is some positive integers m ,n ,m not equal to n , Tm=1÷n , Tn =1÷m then find the value of a-d

Question

Arun · Answer

Tm = 1/n Hence a + (m-1) d = 1/n Similarly a + (n-1) d = 1/m Now solve both the equations d = 1/mn Hence a = 1/mn Now a-d = 0
