If p times the pth term and q times the qth term of an A.P are equal, then prove thatits (p+q)th term is zero.
Let a and d be respetively the first term and the common diff of the A.P.
pth term =a+(p-1)d
qth term =a+(q-1)d
Acc to qn
since p is not equal to q,so p-q can't b equal to zero.
thus the (p+q)th term is equal to zero.
pl chk the qn which you have given again. However we have solved another question of similar type for you.
