A part-time employee tracks their daily tips for a week. The amounts earned (in dollars) are: ${}4, 9, 12, 17, 20, 25$. To determine if this sequence is arithmetic, the employee calculates the differences between consecutive days. Based on the definition of an arithmetic sequence, which statement is true?

A manufacturing plant supervisor is analyzing different production and quality metrics over several shifts. Match each sequence of recorded values to its correct mathematical classification based on whether it represents an arithmetic sequence and what its common difference is.

A warehouse supervisor tracks the stock of a specific part, which decreases by the same amount each week: ${}1000, 950, 900, 850$. Because the difference between any two consecutive weeks is a constant value of -50, this pattern of values is classified as a(n) ____ sequence.

True or False: A quality control technician monitors the daily output of a production line and records the following values over five days: ${}12, 18, 24, 31, 38$. This sequence is classified as arithmetic because the daily output is consistently increasing.

A logistics manager is reviewing a series of cargo weights to determine if the progression follows an arithmetic pattern: ${}40, 45, 50, 55, 60$ tons. Arrange the following steps in the correct order to verify if this data set represents an arithmetic sequence.
