Question

A(n)= -5+ (n=1)(4)
I need help with this answer please

Answer 1

A=-1

Explanation:

A(n)=-5+(1)(4)

A(n)=-5+4

A(n)=-1

A(1)=-1

A=-1

Answer 2

`A_n=A_(n-1)+4 \\ A_1= - 5`

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`
