The formula that defines the sequence is f(n) = f(n-1) + 4
<h3>Recursive function</h3>
The recursive function rule is expressed as;
f(n) = f(n-1) + d
where
d is the common difference
Given the following sequence
2, 6, 10, 14, 18..
Determine the common difference
d = 6-2 = 10-6
d = 4
Substitute to have
f(n) = f(n-1) + d
f(n) = f(n-1) + 4
Hence the formula that defines the sequence is f(n) = f(n-1) + 4

Answer:
$60.95
Step-by-step explanation:
First find the total cost of the two meals w/o the tip.
20.25 + 32.75 = 53
Now find what 15% of 53 is by multiply 53 and 0.15 (move the decimal point twice to the left).
53 * 0.15 = 7.95
Add the tip to the total cost of the meals.
53 + 7.95 = 60.95
The total cost is $60.95.
