Answer:

B. 4n+2

Step-by-step explanation:

You are given the pattern 6, 10, 14, 18, 22

Rewrite it as

$a_1=6\\ \\a_2=10\\ \\a_3=14\\ \\a_4=18\\ \\a_5=22$

Note that

$a_2-a_1=a_3-a_2=a_4-a_3=a_5-a_4=4$

This means that given pattern is a part of arithmetic sequence with

$a_1=6\\ \\d=4$

So, the nth term of this arithmetic sequence is

$a_n=a_1+(n-1)d\\ \\a_n=6+4(n-1)\\ \\a_n=6+4n-4\\ \\a_n=4n+2$

Answer:

Well it definitely can't be a function

Step-by-step explanation:

To find out if a graph is a function, you can use the vertical line test. The vertical line test is when you draw a line down the center and if it hits one point, it's a function. But, when it hits more than one point, it's not. In this case, a line would hit more than one point; meaning that they are not functions.
