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=`

What is the n^(th) term of an A.P. whose first term is 'a' and common difference is 'd'?

Let T_r be the rth term of an A.P. whose first term is a and common difference is d. If for some positive integers, m,n, m ne n, T_m =1/n and T_n=1/m , then a-d equals :

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

Let T be the r th term of an A.P. whose first term is a and conmon difference is d . If for some positive integers m ,n, T_(n)= (1)/(m) , T_(m) = (1)/(n) then (a – d) equals

Let t_(r ) be the rth term of an A.P. whose first terms is 'a' and common difference is d. If for some positive integers, m, n (m ne n) T_(m)= (1)/(n) and T_(n)= (1)/(m) , then a-d=

Let T_(r ) be the rth term of an A.P. whose first term is a and common difference is d. If for some positive integers, m,n,mcancel(=)n, T_(n) = ( 1)/( n ) and T_(n) = ( 1)/( m) , then a -d equals :

If a_n is the n^(th) term of an A.P whose first term is a and common difference is d, prove that n=(a_n-a)/d+1

The nth term of an A.P. whose first term is 'a' and common difference d' is a + (n - 1) d . Prove by PMI.

If T_(r) be the rth term of an A.P. with first term a and common difference d, T_(m)=1/n and T_(n)=1/m then a-d equals

Let T_r be the rth term of an A.P. whose first term is -1/2 and common difference is 1, then sum_(r=1)^n sqrt(1+ T_r T_(r+1) T_(r+2) T_(r+3))
