a.
In order to find the common ratio, we just need to divide a term by the term that comes before it.
So using the terms 20 and -5, we have:
b.
The recursive rule can be found with the formula:
Where an is the nth term and q is the ratio. So we have:
c.
The explicit rule can be written as:
Where an is the nth term, a1 is the first term and q is the ratio. So:
If they don't stop 1 hour and a half.

Answer:
-22k - 67m
Step-by-step explanation:
You have to use the Distributive property:
8(k + m) - 15 (2k + 5m)
8k + 8m - 30k - 75m
Now simplify:
8k - 30k + 8m - 75m
-22k - 67m
Be careful with positives and negatives!
