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.

Answer:
the dimensions of the toy box:
Step-by-step explanation:
x+1=2x
2x-5
90
like terms;
- crossing over becomes + and vice versa
soo 2x-2x +90-5
2x^2 cancels it self out leaving 90-5
=85.
First, we add the numbers. This gives us 715.
Then, we divide it by the amount of numbers. This gives us. 715 divided by 11.
This simplifies to 65.
