Question Write a recursive formula for the arithmetic sequence $-38, -26, -14, -2, \ldots$. Find $a_1$ and $a_n$ for $n \geq 2$.

Studdy Solution
Combine the expressions for $a_1$ and the recursive formula for $a_n$ to complete the answer.
$$\begin{array}{l} a_{1}=-38 \\ a_{n}=a_{n-1} + 12 \text{ for } n \geq 2 \end{array}$$
This is the recursive formula for the given arithmetic sequence.
