Answer» Given that, mth term=1/n and nth term=1/m. then ,let a and d be the first term and the common difference of the A.P.so a+(m-1)d=1/n...........(1) and a+(n-1)d=1/m...........(2).subtracting equation (1) by (2) we get,md-d-nd+d=1/n-1/m=>d(m-n)=m-n/mn=>d=1/mn. again if we put this value in equation (1) or (2) we get, a=1/mn. then, let A be the mnth term of the APa+(mn-1)d=1/mn+1+(-1/mn)=1 |
