- If a,b,c are in A.P and X,Y,Z are in G.P then prove( Xb-c)x (Yc-a) x(Za-b)=1
- In a G.P tp+q=m and tp-q=n. Then find tp.
The question should be;
If a,b,c are in A.P and X,Y,Z are in G.P then prove( Xb-c)x (Yc-a) x(Za-b)=1given: a , b and c are in AP. therefore
or
X , Y and Z are in GP, therefore
LHS of the given equation:
which is the required result.
hope this helps you.
cheers!!
