First sequence is Arithmetic because the common difference is 4.
Second sequence is Geometric because it is multiplied by -2 each time.
Hope this helps :)
Almost. Where you put -(-5) and then later on you say it’s -5. It’s not. It would be +5 or just 5 because - and - makes a plus :)
Consider number 17. You know that
17=9+8.
Then for negative numbers you have the same rule (with respect to sign -):
-17=(-9)+(-8).
Since (-9)+9=9+(-9)=9-9=0, you have that
-17+9=(-9)+(-8)+9=(-9+9)+(-8)=0+(-8)=-8.
Answer: -17=(-9)+(-8).
