Let \( x \) and \( y \) be real numbers such that \( x, x+2 y \) and
\( \mathrm{P} \)
\( 2 x+y \) are in \( A P \) and \( (y+1)^{2}, x y+5 \) and \( (x+1)^{2} \) are in \( G P \). With this information, answer the following questions.
The common ratio of the \( G P \) is
(1) 2
(2) \( 1 / 2 \)
(3) 3
(4) \( 1 / 3 \)
