Achilles ordered a pizza with 16 slices. every hour, he ate half of the remaining slices. let f(n) be the number of slices achilles ate in the nth hour since he got it. f is a sequence. what kind of sequence is it? a. arithmetic b. geometric write an explicit formula for the sequence. f(x)=? will give brainliest answer (if it is right)

The answer is  a) arithmetic 

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.
