Question

In November, the daily low temperature decreases by 2 degrees F each day. Which of the following arithmetic sequences could represent the daily low temperature?

A. −2, −4, −8, −16, −32, …
B. −8, −6, −4, −2, 0, …
C. 2, −4, 8, −16, 32, …
D. 8, 6, 4, 2, 0, …

Answer 1

The correct arithmetic sequence that represents the daily low temperature decreasing by 2 degrees Fahrenheit each day is option B: -8, -6, -4, -2, 0, ..., showing a constant decrease of 2 degrees between consecutive terms.

Step-by-step explanation:

The question asks which arithmetic sequence could represent the daily low temperature in November, decreasing by 2 degrees Fahrenheit each day. An arithmetic sequence is a sequence of numbers with a constant difference between consecutive terms. Looking at the choices, option B: -8, -6, -4, -2, 0, ... is the correct arithmetic sequence that matches the criterion of decreasing by 2 degrees Fahrenheit each day. Each term is increased by 2, giving the appearance of a decrease in temperature when considering daily low temperatures.
