Given: a + (n - 1)d = m

a + (m - 1)d = n

"a'' is first term of the series and d is the common ratio.

Subtracting the two equations, we get

d = -1

Substituting the value of d in 1st eq.

a = m + n - 1

Now, (m + n)th term is

a + (m + n - 1)d

Substitute values of a and d

We get the term equal to 0.
