If `a , b ,a n dc` are in G.P., then `a+b ,2b ,a n db+c` are in a. A.P b. G.P. c. H.P. d. none of these

If a^(2)+b^(2),ab+bc, and b^(2)+c^(2) are in G.P. then a,b,c are in a.A.P.b.G.P.c.H.P.d.none of these

If a,b,c are in A.P.the (a)/(bc),(1)/(c),(2)/(b) will be in a. A.P b.G.P.c.H.P.d.none of these

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 x,y,z are in A.P. then : yz,zx,xy are in (a) A.P (b) G.P (c) H.P (d) no definite sequence

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 the numbers p,q,r are in A.P. then m^(7p), m^(7q), m^(7r)(mgt0) are in (A) A.P. (B) G.P. (C) H.P. (D) none of these

If a,b,c are in A.P. as well as in G.P. then

If a,b,c,d………are in G.P., then show that (a+b)^2, (b+c)^2, (c+d)^2 are in G.P.

If a,b,c,d………are in G.P., then show that (a-b)^2, (b-c)^2, (c-d)^2 are in G.P.
