As per given by the question,

There are given the sequence, -5, -8, -11, and -14.

Now,

For find the recursive formula,

There is need to know about the common difference.

Then,

From the given sequence, the common difference is;


\begin{gathered} -8-(-5)=-8+5 \\ =-3 \end{gathered}

So,

here, d=-3.

Now,

The recursive formula is,
