If `a`, `b`, `c` are real numbers forming an `A.P.` and `3+a`, `2+b`, `3+c` are in `G.P.` , then minimum value of `ac` is

a,b,c are real numbers forming an A.P.and 3+a,2+b,3+c are in GP,then minimum value of ac is

If a, b, c are distinct real numbers such that a, b, c are in A.P. and a^2, b^2, c^2 are in H. P , then

If a,b,c are three unequal numbers such that a,b,c are in A.P. and (b-a) ,. (c-b) ,a are in G.P., then the value of a:b: c is-

If a,b,c are unequal numbers such that a,b,c are in A.P and b - a, c - b, a are in G.P., then a : b : c is

If a,b,c are unequal numbers in A.P. such that a,b-c,c-a are in G.P. then

If a,b,c are unequal numbers in A.P. such that a,b-c,c-a are in G.P. then
