Answer:
geometric with r = 
Step-by-step explanation:
An arithmetic sequence has a common difference (d) between consecutive terms
2 - 4 = - 2
1 - 2 = - 1
Then d is not common , not an arithmetic sequence
A geometric sequence has a common ratio (r ) between consecutive terms
2 ÷ 4 = 0.5
1 ÷ 2 = 0.5
Then common ratio r = 
Thus sequence is geometric
Answer: $19.02
Step-by-step explanation:
First find the sales tax paid. It will be paid on the cost of the meal:
= 14.20 * 8%
= $1.14
Then find the tip which was done after the sales tax was added:
= 24% * (14.20 + 1.14)
= 24% * 15.34
= $3.68
The total cost is:
= Gross amount + Sales tax + tip
= 14.20 + 1.14 + 3.68
= $19.02
