Let a sequence be defined by `a_1=1,a_2=1` and `a_n=a_(n-1)+a_(n-2)` for all `n >2,` Find `(a_(n+1))/(a_n)` for `n=1,2,3, 4.`

Explanation

To solve the problem, we need to find the values of \( a_n \) for \( n = 1, 2, 3, 4 \) using the given recursive formula, and then compute \( \frac{a_{n+1}}{a_n} \) for these values of \( n \).

### Step-by-Step Solution:

1. **Identify the initial values:**
- We are given:
\[
a_1 = 1, \quad a_2 = 1
