Let `T_r` denote the rth term of a G.P. for `r=1,2,3,` If for some positive integers `ma n dn ,` we have `T_m=1//n^2` and `T_n=1//m^2` , then find the value of `T_(m+n//2.)`

Let T_(r) be the rth term of an AP, for r=1,2,… If for some positive integers m and n, we have T_(m)=(1)/(n) and T_(n)=(1)/(m)," the "T_(m+n) equals

Let T , be the r th term of an AP, for r=1,2,3dot if for some positive integers m , n we have T_m=1/n and T_n=1/m , then T_(m n) equals (1998, 2M) 1/(m n) (b) 1/m+1/n 1 (d) 0

Let T_(r) be the rth term of an A.P.for r=1,2,3,...... If for some positive integers m,n, we have T_(m)=(1)/(n)andT_(n)=(1)/(m), then T_(mn) equals a.(1)/(mn) b.(1)/(m)+(1)/(n) c.1 d.0

Let T_(r) be the r^(th) term of an A.P whose first term is a and common difference is d IF for some integer m,n,T_(m)=(1)/(n) and T_(n)=(1)/(m) then a-d=
