I am so not good at math at all
Hi there!
Ok i would love to answer you but do you have answer choices, or the other part of the question or a image?

In mathematics, numbered sequential patterns are distinguished as progressions. There are three types of progression: arithmetic, geometric and harmonic. Let's focus on the arithmetic progression.
The pattern in the arithmetic progression is the common difference, You will find that when you subtract two consecutive terms of the sequence, you would get a common difference. Let's investigate further:
28-44 = -16
12-28 = -16
-4-12 = -16
Thus, the common difference is -16. To know the last term, just simply add -16 to the very last known term. In this case, -4+-16 = -20. The answer is -20.
Hi! :)
12 a^2 + 60 a - 8
- (16 a^2 - 32 a + 9)
= -4 a^2 + 92 a - 17
