If `a ,b ,c ,d in R^+`and `a ,b ,c,d` are in H.P., then (a)`a+d > b+c` (b)`a+b > c+d` (c)`a+c > b+d` (d)none of these``

If a,b,c,in R^(+) , and a,b,c, d are in H.P. then

If a,b,c are in AP and b,c,d be in HP, then

If a,b,c,d are in H.P.then prove that a+d>b+c

If a,b,c,d are positive numbers such that a,b,c are in A.P. and b,c,d are in H.P., then : (A) ab=cd (B) ac=bd (C) ad=bc (D)none of these

If a,b,c, are in A.P., b,c,d are in G.P. and c,d,e, are in H.P., then a,c,e are in

If a,b,c are in H.P , b,c,d are in G.P and c,d,e are in A.P. , then the value of e is

If a,b,c,d are in G.P.,prove that a+b,b+c,c+d are also in G.P.

If a,b,c are in A.P ,then 3^(a),3^(b),3^(c) shall be in (A) A.P (B) G.P (C) H.P (D) None of these

If a,b,c are is AP; b,c,d are is GP and c,d, c are is H.P then a,c,c are is
