Answer:a. Arithmetic

b.

c.

Step-by-step explanation:A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.

In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is

ARITHMETIC ✔️The recursive formula will be the following:

The explicit formula is the following:
