Let

{T_r}

, be

r

th term of an AP whose first term is

a

and common difference is

d

. If for some positive integers

m,n,m \ne n,\;{T_m} = \frac{1}{n}

and

{T_n} = \frac{1}{m}

, then

a - d

equals

View answer and explanation

Correct option: A

Option A (0) is correct because solving the given conditions for an A.P. leads to a - d = 0.
