I feel like the answer is definitely B) -1 < x < 1, but I need to double-check the conditions for convergence.

I'm not entirely sure about the boundaries. Could it be -5 < x < 5? That seems a bit too broad, right?

I think we practiced a similar question where we had to find the range of x for convergence. Was it something like -1 < x < 1?

I remember that for a geometric series to converge, the absolute value of the common ratio must be less than 1.
