Isaac keeps track of the miles per gallon his car gets per week. He has accumulated the following data: (1, 24), (2, 24.48), (3, 24.97), (4, 25.47)

What is the common difference or ratio?

The common difference is 0.48.

The common difference is 0.50.

The common ratio is 0.98.

The common ratio is 1.02.

The common ratio is 1.02
Step-by-step explanation:
An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.
From data the differences between two consecutive terms are:
24.48 - 24 = 0.48
24.97 - 24.48 = 0.49
25.47 - 24.97 = 0.5
Then, there is no common difference and the sequence is not arithmetic.
From data the ratio between two consecutive terms terms are:
24.48/24 = 1.02
24.97/24.48 = 1.02
25.47/24.97 = 1.02
Then, the common ratio is 1.02 and the sequence is a geometric one.
