Answer:
The explicit equation is a(n) = 8*(5/8)^(n - 1).
The domain is [0, ā ).
Step-by-step explanation:
If the first term is 8 and the second term is 5, we get to 5 by multiplying 8 by 5/8:
(5/8)(8) = 5
Thus, the common ratio of this geometric sequence is 5/8.
The explicit equation is a(n) = 8*(5/8)^(n - 1).
The domain is [0, ā ).
