The temperature (in °C) recorded at noon during the first four days of a week was 24.0, 25.5, 27.2, and 29.1.
If the same pattern continues, what will be the expected temperature on the 6th day?
Show answer & explanation
Correct answer: C
Explanation
25.5 − 24.0 = 1.5
27.2 − 25.5 = 1.7
29.1 − 27.2 = 1.9
The difference is increasing by 0.2°C each time.
So,
Increase on day 5 = 2.1°C
29.1 + 2.1 = 31.2°C
Increase on day 6 = 2.3°C
31.2 + 2.3 = 33.5°C
