Answer:
Explanation:
as the day went on the temperature rose 3° each hour. This is a linear rate. The rate at which the temperature is increasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = -7 Fahrenheit
d = 3 degrees Fahrenheit
n = number of hours over time
The equation that shows the temperature over time would be
Tn = - 7 + (n - 1)3
Tn = - 7 + 3n - 3
Tn = - 10 + 3n
