The ...The nth term of this AP is Tn=4+(n-1)3=3n+1 <br /><br />The series is 4,7,10,13....<br /><br />By inspection the squares are 16,49,100,169 ..if these are part of the same AP then they should satisfy the equation 3n+1 because they would be "some term" of the AP, what we need to find is which term of the AP is square of 4,7,10,13 etc <br /><br />So for 16 we can say 16=3n+1 gives n=5 <br />for 49 we can say 49=3n+1 giving n=16<br />for 100 we can say 100=3n+1 giving n=33 and so on ...<br /><br />We see from the above that squares satisfy the nth term and hence would be part of the AP.<br /><br />For video lessons and free doubt clearing,please visit our site www.sslc.mystudypark.com <br /><br />Thanks Anonymoushttps://www.blogger.com/profile/09385535933335893115noreply@blogger.comtag:blogger.com,1999:blog-2787161678592839240.post-5606701873730636592015-08-02T20:19:47.172+05:302015-08-02T20:19:47.172+05:30please give me the answer to the following questi...please give me the answer to the following question :-prove that the squares of all terms the A.P.4,7,10,13,......includes in the same A.P.Anonymoushttps://www.blogger.com/profile/16258151890778883860noreply@blogger.comtag:blogger.com,1999:blog-2787161678592839240.post-18056420984599351112015-08-02T20:19:21.465+05:302015-08-02T20:19:21.465+05:30please give me the answer to the following questi...please give me the answer to the following question :-prove that the squares of all terms the A.P.4,7,10,13,......includes in the same A.P.Anonymoushttps://www.blogger.com/profile/16258151890778883860noreply@blogger.comtag:blogger.com,1999:blog-2787161678592839240.post-49435187601834870742015-07-30T17:37:33.369+05:302015-07-30T17:37:33.369+05:30please give us also the answer sheets sir........
