<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given that the price of gas started at $2.25 and increased at a rate of 4% per year.
We are to write a function which models this situation using numerical values of A and r into the expression.
A = $2.25
r = 4%
Assuming x to be the time in years, the function would be:

Answer:
answer is 46.
Step-by-step explanation:

Answer:
an = 5·2^(n-1)
Step-by-step explanation:
The explicit formula for a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
Your sequence has a1=5 and r=2, so the explicit formula is ...
an = 5·2^(n-1)
Answer:
d
