Answer:
1. 45, 51
2. 40, 52
3. -64, 128
4. 63.5, 63.75
Explanation:
1. It is adding 6 each time.
2. It adds 2, then 4, then 6, each time adding an extra 2 units. (another way to explain is, the original term, 2, that they add is multiplied by 2 each time)
3. It multiplies by -2 each time.
4. It adds 16, then 8, then 4, dividing the term that is added by 2 each time.
Attention:
I didn't do the bottom half of the homework, I will leave that for someone else to get the points. I hope this helps you. :)
