Problem
Write an explicit formula that represents the sequence defined by the following recursive formula: \[ a_{1}=96 \text { and } a_{n}=-\frac{1}{4} a_{n-1} \] Answer: \( a_{n}= \) Submit Answer attempt 1 ou
Solution
Step 1 ：\(a_{1} = 96\)
Step 2 ：\(a_{n} = -\frac{1}{4} \cdot a_{n-1}\)
Step 3 ：\(a_{n} = 96(-\frac{1}{4})^{n-1}\)
