Answer: 
<u>Step-by-step explanation:</u>
Term-to-term rule is also called the recursive rule.
The recursive rule for a geometric sequence is:
where

- r is the common ratio
The common ratio (r) is the second term divided by the first term <em>(which is the same ratio for each term divided by its previous term) </em>
In the given sequence {64, 32, 16, 8, 4}, 
So, the recursive rule is: 
The slope is a negative slope and the y-intercept is (0,2).
With my calculation it says 55.5
( Sorry if incorrect)
Answer:
14 9/16 - 8 1/4 = 14 9/16 - 8 4/16 = 233/16 - 132/16 = 101/16 = 6 5/16 ~~ 6
14 9/16 - 8 1/4 = 6
