If three positive numbers a,b and c are in AP, GP and HP as well, than find their values.

If first and (2n-1)^th terms of an AP, GP. and HP. are equal and their nth terms are a, b, c respectively, then (a) a=b=c (b)a+c=b (c) a>b>c and ac-b^2=0 (d) none of these

Problem Solving of AP,GP,HP,AGP

Let the positive numbers a,b,c,d be in AP. Then abc,abd,acd,bcd are (2001,1M) not in AP/GP/HP ( b ) in AP in GP (d) in HP

If a,b,c are in AP or GP or HP,then (a-b)/(b-c) is equal to

Let the positive numebrs a,b,c,d be in A.P. Then abc,abd,acd,bcd re (A) not in A.P., G.P., H.P. (B) in A.P. (C) in G.P. (D) in H.P.

If a, b, c are in AP or GP ot HP where a>0, b>0, c>0 then prove that b^2> or = or < ac .
