Question

Which of the following represents an arithmetic sequence?

The temperature rises by one degree the first hour and then falls two degrees the second hour.
The temperature rises two degrees the first hour, another two degrees the second hour, and so on.
The temperature rises and falls at different rates during the day.
The temperature rises one degree the first hour, 2 degrees the second hour, 4 degrees the third, and so on.

Answer 1

[AI-generated answer — Bot]

The temperature rises one degree the first hour, 2 degrees the second hour, 4 degrees the third, and so on. This represents an arithmetic sequence because the temperature is increasing or decreasing by a constant amount (in this case, by 1 degree, then by 2 degrees, and so on) in each interval.
