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

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.

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.

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 and b,c,d be in HP, then

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

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

If a, b, c are in A.P. and a,b, d are in G.P., prove that a, a-b, d-c are in G.P.

If a, b, c are in AP and a, b, d are in GP, show that a, (a-b) and (d-c) are in GP.

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
