<h3>
Answer: B. Yes, d = 3</h3>
==============================================================
Explanation:
d = common difference, which is what we add on each time to get the next term
In this case, d = 3 means we add 3 each time to generate each new term
- -11+3 = -8
- -8+3 = -5
- -5+3 = -2
- -2+3 = 1
This pattern continues on forever.
--------------
Another way to see that d = 3 is to notice this is the difference between any two adjacent terms.
- d = term2 - term1 = -8 - (-11) = -8 + 11 = 3
- d = term3 - term2 = -5 - (-8) = -5 + 8 = 3
- d = term4 - term3 = -2 - (-5) = -2+5 = 3
- d = term5 - term4 = 1 - (-2) = 1 + 2 = 3
Each gap is 3 units wide, which helps us see we have an arithmetic sequence.
A sequence like {-11,-8,-5,-2,2} is not arithmetic because the gap between the terms of -11,-8,-5,-2 is 3, but the gap from -2 to 2 is not 3. So the gap must stay the same the entire time to get an arithmetic sequence.
0.0206 that is it hope it helps
For this you have to find the area.
To find the area you multiply the width by the length.
You multiply 12 by 8 and you get 96.
Did you notice that it said SQUARE YARDS OF CARPET , we have convert 96 feet to yards.
1 yard= 3 feet
So you divide 96 by 3 and you get 32.
Amy needs 32 square yards of carpet to complete the room.
