1.	An AP consist of 50terms of which 3rd term is 12 and the last term is 106 . Find the 29th term
Answer» Let the first term be a and common difference be dTn=a+(n-1)dA/qa+2d=12---------1a+49d=106-------2With equation 1&2 we have; By changing signa+2d=12-a-49d=-106-47d=-94d=2Putting d value in eq 1a+2(2)=12a=12-4a=8Now; 28th term=a+27d =8+27(2) =8+54=62Hence; 28th term is 62 ansHope this will right .
