If the straight line `a x+c y=2b ,` where `a , b , c >0,` makes a triangle of area 2 sq. units with the coordinate axes, then (a)`a , b , c` are in GP (b)a, -b; c are in GP (c)`a ,2b ,c` are in GP (d) `a ,-2b ,c` are in GP

If the straight line a x+c y=2b , where a , b , c >0, makes a triangle of area 2 sq. units with the coordinate axes, then (a) a , b , c are in GP (b) a, -b, c are in GP (c) a ,2b ,c are in GP (d) a ,-2b ,c are in GP

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 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 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 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, and c are in G.P then a+b,2b and b+ c are in

If a, b, c are in AP amd b, c, a are in GP , then show that c, a, b are in H.P. Find a : b : c .

If bx+cy=a , there a, b, c are of the same sign, be a line such that the area enclosed by the line and the axes of reference is 1/8 square units, then : (A) b,a,c are in G.P. (B) b, 2a, c arein G.P. (C) b, a/2, c are in A.P. (D) b, -2a, c are in G.P.

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

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then
