Answer:

Next term = -16
Step-by-step explanation:

0-4 = -4
(-4)-0 = -4
(-8)-(-4) = -4
(-12)-(-8) = -4
It’s clear that Un is an arithmetic sequence of common difference r = -4
Then

Next term :

1 plus 1 equals 2 ,2 times 0 equals 0 .get it.
9x^3-6x^2+3x
Basically with this you just wanna simplify each term one-by-one.
For instance, look at the first term, 27x^4
Imagine 27x^4/3x
3 goes into 27 9 times, and x goes into x^4 4 times (cuz x to the power of 4 is just x times x times x times x)
So you’re left with 9x^3
-6 i belive. but i don’t really think it’s the answer so put what u want but i’m not sure
