Yes it is because none out the inputs have the same outputs
Answer:
x=2
Step-by-step explanation:
2*2-x=2
4-x=2 subtract 4 by both sides
-x= -2 multiply each side by -1
x=2 answer

dividing both sides by -4, we get:

this means, each term is its previous term divided by -4.
now we can construct the sequence as follows:




Answer: the last term is -1/32
Answer: 5th degree trinomial
The degree is 5 because its the largest exponent of the single variable polynomial.
It's a trinomial because there are 3 terms. The terms are separated by a plus or a minus.
