Full solution stays hidden until you ask for it.
1. Confirm input intervals are equal.
2. Divide each output by the previous output.
3. Constant ratios indicate an exponential pattern.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
