ANSWER
The common difference is
EXPLANATION
We want to find the common difference of the arithmetic sequence,
The common difference is the constant difference between any two consecutive terms.
Thus,
For instance the first and second term of the sequence has the difference,
Or the third and the second term has the difference,
Since this is an arithmetic sequence the difference is the same for any two consecutive terms.

Using the sinusoidal function, it is found that the temperature will be below 0ºC between May and August.
<h3>What is a Sinusoidal function?</h3>- A sinusoidal function is a function that depends on a trigonometric function, having peaks according to the period and amplitude given by this function.
The function for the average monthly temperature, in m months after January, is given by:
Working with elementary angles, we have that:
From this, we have that it becomes negative after March, and positive before September, removing the middle two options.
Now, we have to test for April and May, that is, m = 4 and m = 5, hence:
Negative only in May, hence the temperature will be below 0ºC between May and August.
