Answers:
1, 6, 36, 216: Geometric
12, 4, -4, -12: Arithmetic
1, 2, 8, 64: Neither
-216, -72, -24, -8: Geometric
Explanations:
Arithmetic Sequence: Every number in the sequence is either added or subtracted by the same number. We know that 12, 4, -4, -12 is arithmetic because each number in the sequence is subtracted by 8.
Geometric Sequence: Every number in the sequence is either multiplied or divided by the same number. We know that 1, 6, 36, 216 is geometric because each number in the sequence is multiplied by 6. We also know that -216, -72, -24, -8 is geometric because each number in the sequence is being divided by 3.
Neither: 1, 2, 8, 64 is neither because it is not being added, subtracted, multiplied, or divided by the same number.
I hope this helped!

7*1+8
mult first
7*1=7
7+8=15
nw we have
1/2*(15)+11
multiply 1/2 and 15 and get 15/2=7 and 1/2
then add 11
7+11=18
18 and 1/2 is answer or 37/2 or 18.5
Answer: You could say that it gives a reasonable accurate measure for most students.
If you use the function, you will get the following values for each student.
Mike 86, Terrel 50, Janie 66, and Melissa 106
For the first two students, the equation produces a score that is almost perfect. For the second two students, the scores are off by 14 and 16.
Overall, it is not a bad trendline for the data.
1 ton = 2000 lbs
so 4 tons = 4 * 2000 = 8000 lbs
at 0.60 per lb...
8000(0.6) = $ 4800 <==
