This problem is half understanding the question and half just plugging in numbers. 
Understanding the Question:So its saying that n = whole number bigger than one, making n = 2, 3, 4, 5, etc.
Now try plugging any number n into the 

 equation. Let's use 2 to make it simple. If you plug in 2, you get:

Remember that the subscripts (the small numbers in the corner) are simply the term number. 

 is term 1, 

 is term 2, etc. The equation is saying that "term 2 = 4 times term 1." 
If you keep plugging in random numbers for n, you'll see that the equation basically says, "a term = 4 times the term right before it." That makes it easy to plug and chug to get our answer.
Plugging and Chugging
Now we understand the question is asking for the first 4 terms, and each term is 4 times the last term. You're told that term 1, 

 = 6. That makes the next four terms:
Term 2

Term 3

Term 4

Your first 4 terms are 4, 24, 96, and 384.

Answer: A) F
 
        
        
        
Answer:
A
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent in the terms of the polynomial. The leading coefficient is the coefficient of the term with the largest exponent.
Given
f(x) = 2x³ + 2x² - 
The term -  means that f(x) is not a polynomial
 means that f(x) is not a polynomial
Since terms with division by a variable are not allowed.

Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877
