r th term of an ap= Tr 

m th term of an ap= Tm 

n th term of an ap= Tn 

As indicated by question m.Tm=n.Tn 

m(a + (m-1)d = n(a + (n-1)d) 

Where an is the principal term and d is the normal distinction 

mama – na + (m^2 – m)d - (n^2 –n)d 

a(m-n) + d(m-n){m+n-1} = 0 

a + (m+n-1)d = 0 

Tm+n=0 

Thus Proved
