The common difference of the AP (1)/(p), (1-p)/(p), (1-2p)/(p) ,…. Is

The common difference of the AP (1)/(p),(1-p)/(p),(1-2p)/(p)...... is

. 1/(p+q),1/(q+r),1/(r+p) are in AP, then

If a,b,c are in A.P., b,c,d are in G.P. and (1)/(c ),(1)/(d),(1)/(e ) are in A.P, prove that a,c,e are in G.P.

if a, b, c are in A.P., b, c, d are in G.P. and (1)/(c),(1)/(d),(1)/(e) are in A.P., then prove that a, c, e are in G.P.

If a,b,c are in A.P,prove that (1)/(bc),(1)/(ca),(1)/(ab), is also in A.P.

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 a(a != 0) is a fixed real number and (a-x)/(p x) = (a-y)/(qy) = (a-z)/(r z) . If p, q, r are in A.P., show that (1)/(x), (1)/(y), (1)/(z) are in A.P.

If (1)/(x) , (1)/(y) , (1)/(z) are A.P. show that xy,zx,yz are in A.P.
