Answer 2

Answer:

$A_n=A_{n-1}+4 \\ A_1= - 5$

Step-by-step explanation:

Assuming you want to write a recursive formula, for

$A_n = - 5 + (n - 1)(4)$

We recall that d=4, is the common difference in this explicit definition.

The recursive formula is given by:

$A_n=A_{n-1}+d$

We substitute to get:

$A_n=A_{n-1}+4$
