If a,b,c,d are in continuous proportion then prove that (c+a) (c+d) = (b+c) (b+d)

sesenic [268]

Answer:

We must prove that (c+a)(c+d) = (b+c)(b+d)

Let us use principles from mathematical induction
$\frac{a}{b} = \frac{b}{c} = \frac{c}{d} = x$
a=bx , b=cx, c=dx
a+c = b + c
c +d = b + d
Such that (a+c)(c+d)=(b+c)(b+d)
