a mercury thermometer records a temperature of 8 degrees fahrenheit at 10 a. m. if the temperature drops by 3 degrees fahrenheit every hour what will be the temperature by 2 p. m. of the same day

-4 Degrees Fahrenheit

Step-by-step explanation:

Given

---- at 10am

Required

Determine the final temperature at 2pm

First, we need to determine the hour from 10am to 2pm (Both inclusive)

To solve further, we make use of the following Arithmetic Progression formula:

Where

--- Initial

--- difference

-- 5th term

--- Final temperature at 2pm

So: we have:

Hence:

The temperature is -4 Degrees Fahrenheit
