We can say that this its an arithmetic sequence because it has a common difference:

d=303-309=-6

d=297-303=-6

Arithmetic sequences are represented by the following expression:

[tex]a_n=a_1+(n-1)d[/tex]

Where,

an=The term we want to find

a1= first term of the sequence

n= term position

d=common difference

[tex]\begin{gathered} a_{33}=309-6(33-1) \\ a_{33}=309-192 \\ a_{33}=117_{} \end{gathered}[/tex]
