Answer:
[tex]A_n=A_{n-1}+4 \\ A_1= - 5[/tex]
Step-by-step explanation:
Assuming you want to write a recursive formula, for
[tex]A_n = - 5 + (n - 1)(4)[/tex]
We recall that d=4, is the common difference in this explicit definition.
The recursive formula is given by:
[tex]A_n=A_{n-1}+d[/tex]
We substitute to get:
[tex]A_n=A_{n-1}+4[/tex]
Answer:
A=-1
Step-by-step explanation:
A(n)=-5+(1)(4)
A(n)=-5+4
A(n)=-1
A(1)=-1
A=-1
