determine which sequence is an arithmatic sequence. a. - 10, 5, - 5/2, 5/4, ... b. 1/5, 1/7, 1/9, 1/11, ... c. 3,6, 12, 24, ... d. - 7, - 3, 1, 5, ...

d

Step-by-step explanation:

An arithmetic sequence has a common difference between its terms. The only sequence with a common difference is choice d, which has a common difference of - 4. The other options have common ratios, making them geometric, not arithmetic, sequences.
