Answer: {2, -2, -6, -10}
Arithmetic sequences are defined by a common difference between the numbers that’s both constant and consecutive.
To break it down:
The first option is {-1, 3, -3, -1}, which appears to be alternating, and there is more than 1 difference between the n term values. That is:
-1 to 3 = increase of 4
3 to -3 = decrease of 6
-3 to -1 = increase of 2
Therefore does not follow the definition of an arithmetic sequence.
The second option (the answer) {2, -2, -6, -10} is arithmetic, as it consistently and thus consecutively decreases by 4.
Finally, the last two sequences have the same issue with their pattern, {3, 6, 9, 15}
and {4, 14, 24, 32}. In which they stay constant for the first three n terms, but suddenly change in value on the 4th n term. Therefore, they are not arithmetic.

The correct answers are:
___________________________________________________
[A]: " (0, 0) " ; <u>AND</u>:
___________________________________________________
[C]: " (-2, -1) " .
___________________________________________________
Explanation:
___________________________________________________
[A]: " (0, 0) " ; is correct;
Since, when "x = 0" and y = 0 :
"0 <span> > - 4 " ; which is correct.
</span>___________________________________________________
[B]: "(2, 1)" is incorrect, since:
when "x = 2" and "y = 1" ;
" 1 > 6" ; is incorrect.
___________________________________________________
[C]: "(-2, -1)" ; is correct;
Since, when "x = -2" and y = -1" ; then:
"-2 <span> > -6 ; which is correct.
</span>___________________________________________________
[D]: " (-5, -1) " ; is INCORRECT.
since when "x = -5" and "y = -1 ;
then: -1 > 6 ; which is INCORRECT.

The greater fraction is 6/11
6/11 = 0.54
1/2 = 0.50
Therefore 0.54 which is 6/11 is greater
8) you go up by 2 on the y-axis and over 3 on the x-axis
9) you have to go up 3 on the y-axis and over 2 on the x-axis
But you always have to go over then up
