Answer:
a_n=-50+(n-1)17

Explanation:

The Arithmetic Sequence Formula is:


a_n=a_1+(n-1)d

Where:


a_n is the
n^(th) term of the sequence.


a_1 is the first term of the sequence.


n is the term position.


d is the common difference of any pair of consecutive numbers.

We can observe that the first term is:


a_1=-50

Now, we need to find "d". This is:


d=-16-(-33)\\d=-16+33\\d=17

Then, substituting, we get the following equation:


a_n=-50+(n-1)17
