For an A.P. show that t _(m) + t _(2n + m) = 2 t _(m +n)

For an A.P, show that t_(m)+t_(2n)+m=2t_(m+n)

For an A.P.show that t_(m+n)+t_(m-n)=2t_(m)

In an A.P., prove that : T_(m+n) + T_(m-n) = 2*T_(m)

In an A.P., prove that : T_(m+n) + T_(m-n) = 2*T_(m)

Let T_(r) be the rth term of an A.P. If m. T_(m) = n.T_(n) , the show that, T_(m+n) = 0 .

Let t_(r) denote the r^(th) term of an A.P.Also suppose t_(m)=(1)/(n) and t_(n)=(1)/(m) for some positive integers m and n then which of the following is necessarily a root of the equation? (l+m-2n)x^(2)+(m+n-2l)x+(n+l-2m)=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 ) and T_(n) = ( 1)/( m ) , then T_(mn) equals :
