Step-by-step explanation:

Answer:
- using the rule given: 2.5
- using an exponential rule: 7
Step-by-step explanation:
Evaluating the linear rule given, for n = 1, we have ...
a1 = 7(1/2)(1) -1 = 7/2 -1 = 5/2 = 2.5
_____
We suspect you may intend the exponential function ...
an = 7(1/2)^(n-1)
Then, for n = 1, we have ...
a1 = 7(1/2)^(1 -1) = 7(1) = 7 . . . . the first term is 7
_____
When writing an exponential expression in plain text, it requires the exponential operator, a caret (^). If the exponent contains any arithmetic, as this one does, it must be enclosed in parentheses.
Answer:
1. rate = 30, base = 40, percentage = 12
2. rate = 6, base = 24, percentage = 25
3. rate = 16, base = 64, percentage = 25
4. rate = 4, base = 50, percentage = 20
5. rate = 75, base = 80, percentage = 60
