Answer:
f(n) = 8 - 3f(n-1)
d : { 8 >= x }
Step-by-step explanation:
Basically we know 8 is the first term, so we subtract 3 to get 5 which is the second term. Then we know d = -3. Now we that we established the formula, let's make a domain. We know x can never be greater than 8 so x is always less than or equal to 8.
