Question

edna has been saving $4 from her allowance each week. if you track the total amount saved over time, what kind of sequence will you see? arithmetic geometric both neither

Explanation:

An arithmetic sequence has a common difference between consecutive terms. Here, Edna saves $4 each week. So the total amount saved each week forms an arithmetic - sequence as the difference in the total amount saved from one week to the next is a constant $4. A geometric sequence has a common ratio between consecutive terms. Since the ratio of the total amounts saved each week is not constant (e.g., if she starts with $0 and saves $4 the first week, $8 the second week, $\frac{8}{4}=2$ for the first - two terms but if she saves $12 the third week, $\frac{12}{8} = 1.5$), it is not a geometric sequence.

Answer:

A. arithmetic
