1, if in an a.p ,mtm=ntn then show that tm+n=0
2. if the pth term of an a.p is q and the qth term is p , then find its (p+q) th term.
3. prove that for all finite values of a and b
(a-b)², (a+b)²,a²+b² are in a.p.
4. in the arithmatic sequence 3,7,11, 15............ and 2,5,8..........each continued to 100 terms ,find how many terms are identical.
