If a,b,c and d are four unequal positive numbers which are in A.P then

If a,b,c,d are four different positive numbers which are in A.P then prove that bc gt ad

If a ,b ,c ,d are four distinct positive numbers in G.P. then show that a+d > b+c dot

If a,b,c,d are four distinct positive numbers in G.P.then show that a+d>b+c.

If three unequal positive numbers a, b, c are in G.P. then show that, a +c gt 2b .

If a ,b ,c ,d are four consecutive terms of an increasing A.P., then the roots of the equation (x-a)(x-c)+2015(x-b)(x-d)=0 are

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 a: b : c is :

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 three positive unequal numbers a,b,c are in H.P.,then
