Answer:
- A(1) = -4
- A(n) = A(n - 1) - 6
Step-by-step explanation:
<h3>Given</h3>
- AP with the explicit formula A(n) = 8 - 6(n - 1)
<h3>To find </h3>
<h3>Solution</h3>
<em>Recursive formula is the formula A(n) = A(n - 1) + d</em>
<u>Based on the explicit formula we have:</u>
- A(n) = 8 - 6(n - 1) = 8 - 6n + 6 = 2 - 6n
- A(n - 1) = 2 - 6( n - 1) = 2 - 6n + 6 = 8 - 6n
<u>The common difference is:</u>
- d = A(n) - A(n - 1) = 2 - 6n - (8 - 6n) = 2 - 6n - 8 + 6n = - 6
<u>The first term is:</u>
- A(1) = 2 - 6(1) = 2 - 6 = -4
<u>So the recursive formula is:</u>
- A(1) = -4
- A(n) = A(n - 1) - 6
