Answer:
b. 
Step-by-step explanation:
Here we are given
and are asked to simplify it. We are going to apply the law of exponents which says that

Hence applying this rule in our problem we get, where a=y and n=3

Hence our C) Option is correct
Answer:

Step-by-step explanation:
The recursive rule tells you the initial term of the sequence is a1 = -3, and the common difference is d=7. (7 is the value added to one term to get the next term.)
Putting these values into the formula for the explicit rule gives ...
an = a1 +d(n -1)
an = -3 + 7(n -1)
