Translate the explicit geometric rule a_n = 125(1.5)^(n - 1) into a recursive rule.
Using a hint is okay. It just tells the trainer to give you a little more review.

Hidden until you reveal it.
Explicit rule must be geometric with clear start index and common ratio.
Enter your answer
Your answer is equivalent to the expected form.

Full solution stays hidden until you ask for it.
1. Read the starting term from the coefficient and indexing convention.
2. Read the common ratio from the base.
3. Write each term as the common ratio times the previous term.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Recursive rule with off-by-one first term.
