Which explains why the sequence 81, 3, 1/ is arithmetic or geometric?

The sequence is geometric because it decreases by a factor of 1/27

Ithink the right answer could be 50%

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
