First, we start off with the nth term formula for an arithmetic sequence, which is 
[tex]a_{n} =a_{1}+(n-1)d[/tex]

plug in the sequence numbers where they belong

[tex]a_{n}=5+(n-1)*(-4) [/tex]
[tex]a_{n}=5+(-4n+4)[/tex]
[tex]a_{n}=5-4n+4[/tex]
[tex]a_{n}=-4n+9[/tex]

And this is the final answer
[tex]-4n+9[/tex]
