Since we know the sequence is a geometric sequence, the ratio of consecutive terms is always the same number. Thus, we can set up an equation:
$\frac{2x+2}{x} = \frac{3x+3}{2x+2}$.
Solving it, we get:
$\frac{2x+2}{x} = \frac{3x+3}{2x+2}$
$(2x+2)(2x+2) = (3x+3)(x)$
$4x^2+8x+4 = 3x^2+3x$
$x^2+5x+4 = 0$
$(x + 4)(x+1) = 0$
$x = -4$ or $x = -1$
If $x=-1$, the sequence has a $0$ as the second term, which is not allowed in a geometric sequence, so it is an extraneous solution that came about because we cross-multiplied by $(2x + 2)$, which is $0$.
If $x=-4$, we plug into $x, 2x +2, 3x + 3$ to find the sequence starts as $-4, -6, -9$. The common ratio is $\frac{-6}{-4} = \frac{3}{2}$. The next term is $\frac{3}{2} \cdot -9 = \frac{-27}{2} = -13\frac{1}{2}$, which is option $\textbf{(B)}$
