X5 = X4 / (X4 + 1)
=> X4 / 2 = X4 / (X4 + 1)
=> X4 = 1

X1 = 8

OK, I'm with you up to X4 = 1

How did you get X1 = 8?

Equating the both statements we get the value of x4 and we could proceed by
using statement 1 alone we get x3 value on substitution and similarly x2 and finally x1
x1=8
hence C is the correct option..

X4 = X3/2
X3 = 2 = X2 / 2
X2 = 4 = X1 /2
X4 = 8

AHHHHHHHHHHHHHHH GOT IT

I think I may leave this forum today - am thinking through treacle.

Part of problem was that I was reading 1) as:

Xi = (Xi - 1)/2 instead of Xi = X(i-1)/2

Thanks a lot!
