Which function describes the arithmetic sequence shown? The sequence is : -1, 1, 3, 5, 7, 9, 11, 13

The function describes the arithmetic sequence.

Step-by-step explanation:

Given the sequence

-1, 1, 3, 5, 7, 9, 11, 13

An arithmetic sequence has a constant difference 'd' is defined by

Compute the differences between all the adjacent terms:

As the difference between all of the adjacent terms is the same and equal to

As the first element is

so the term will be:

So, the function describes the arithmetic sequence.
