Let positive number a,b,c ,d be in A.P., then show that abc, acd, bcd are in H.P.

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.

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

Let the positive numbers a ,b ,ca d nd be in the A.P. Then a b c ,a b d ,a c d ,a n db c d are a. not in A.P. /G.P./H.P. b. in A.P. c. in G.P. d. in H.P.

If a^(2),b^(2),c^(2) are in A.P. ,then show that b+c,c+a,a+b are in H.P.

Let a,b,c,d and e be distinct positive numbers. If a,b,c and 1/c,1/d,1/e both are in A.P. And b,c,d are in G.P.then

in three positive numbers a, b and c are in A.P. such that abc = 8, then the minimum possible value of b is
