Answer:
The rule could be an = 6*2^(n-1)
Step-by-step explanation:
If it is a geometric sequence
Fifth term a5 = a1 r^4 where a1 is the first term
a1 r^4 = 96
r^4 = 96/a1
2^4 = 16 and 96/16 = 6 so a1 could be 6
Check: 6*2^(5-1) = 6*2^4 = 96.

Hi there friend, I hope this helps explain a little better. Let me know if you have questions.
Answer:
(x-1)(x^2 + 1)
Step-by-step explanation:
If the polynomial has two roots or zeros, then the least degree it can be is 2. But when x = -i is a root, generally x = i is a root too. Thus the degree here is 3. Using the roots, you can write the polynomial by finding a factor from each. The zeros are the solution to the factor. So if x = 1, it came from the factor x - 1. x = 1 is the solution because x - 1 = 0 is x = 1 solved.
When x = -i, i this is the result of a square root of a negative number. So x had the exponent 2. To write the factor for x = -i, you should write x^2 + 1. When solved x = +/-√-1 = +/- i.
The function is likely (x-1)(x^2 + 1).
