This is just an arithmetic sequence because each term is a constant difference from the preceding term, called the common difference.

Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1)  where a=initial term, d=common difference, n=term number

In this case a=-8 and d=3 so

a(n)=-8+3(n-1)  which you can simplify if you'd like

a(n)=-8+3n-3

a(n)=3n-11
