Question

If m times of mth term of an Ap is equal to n times of nth term ,then find the (m+ n)th term of the Ap​

Answer 1

let the first be and common difference is .

Given m times the mth term = n times the nth term

Recall that the nth term of AP is

Similarly, the mth term of AP is

But,

Hence, (m+n)th term of an AP is zero
