Right, so what single operation could you do to get from -8 to -16?

-8

that could work, but would that work to get you from -16 to -32?
Pandalover485
Best Response

no?? becase 32 - 16 is 16

Correct. Now all three of those numbers that you said (4, 8, 16) have a common factor... What is it?

4...

True, but we are not looking for the GCF here. Wouldn't 2 be a factor for those three numbers?

Okay, so if we have two as a factor. What can we do to the original number (-4) to make it equal -8 while still using 2?

Hint: It's one of the four operations (add, subtract, multiply, divide)

I have to go, here are thw answrs with explinations:
2. B: the rule of multiply 2 holds true for all numbers in the set
3. B: adding two every time gives you all numbers listed there.
