If `(a+b x)/(a-b x)=(b+c x)/(b-c x)=(c+dx)/(c-dx)(x!=0)` , then show that `a ,\ b ,\ c\ a n d\ d` are in G.P.

Explanation

To show that \( a, b, c, d \) are in Geometric Progression (G.P.) given the equation

\[ \frac{a + bx}{a - bx} = \frac{b + cx}{b - cx} = \frac{c + dx}{c - dx} \quad (x \neq 0) \]

we can follow these steps:
