Let

T_r

be the

r^{\text {th }}

term of an A.P. whose first term is a and common difference is

d

. If for some positive integers

m, n

m \neq n, T_m=\frac{1}{n}

and

T_n=\frac{1}{m}

, then

a-d

equals

View answer and explanation

Correct option: D

Option D (0) is correct because a-d equals 0 when solving the equations derived from the given conditions of the arithmetic progression.
