Simply change \(2\) to a \(6\) and \(3\) to a \(4\).
Once you get an interval in the form of \(-1 < x < 5\), put it in interval notation \((-1, 5)\).
Instead of taking \(\frac{a}{1 - r}\) as \(\frac{1}{1 - (\frac{x - 2}{3})}\), you use what you had and change it to like \(\frac{1}{1 - (\frac{x - 6}{4})}\).
You simplify and get the final answer.
