It looks like you've provided a sequence of numbers: -5, -2, 1, 4, 7.

This appears to be an arithmetic sequence because the difference between each consecutive term is constant. Let's find the common difference:

-2 - (-5) = 3
1 - (-2) = 3
4 - 1 = 3
7 - 4 = 3

The common difference is 3. Therefore, this sequence follows the general form of an arithmetic sequence:
$a_n = a_1 + (n-1) \cdot d$
Where:

• $a_1 = -5$ (the first term)
• $d = 3$ (the common difference)
• $n$ is the term number.

Do you want to know more about this sequence, like the next terms or the sum of the terms?
