Best ResponseYou've already chosen the best response.1see which ones have a "common ratio" i.e if you divide one term by the previous one, you always get the same number

Best ResponseYou've already chosen the best response.1not \[–2, –4, –6, –8, –10, …\] since there you are subtracting 2 each time, so it is "arithmetic"

Best ResponseYou've already chosen the best response.1\[16, –8, 4, –2, 1\] is geometric since \[\frac{8}{16}=\frac{8}{8}=\frac{2}{4}=\frac{1}{2}\] all the ratios are \(\frac{1}{2}\)

Best ResponseYou've already chosen the best response.1typo there, i meant \[\frac{8}{16}=\frac{4}{8}=\frac{2}{4}=\frac{1}{2}\]

Best ResponseYou've already chosen the best response.1for \[–15, –18, –21.6, –25.92, –31.104, … \] check using a calculator if \[\frac{18}{15}=\frac{21.6}{18}=\frac{25.92}{21.6}\]
