Best ResponseYou've already chosen the best response.1The domain of any arithmetic or geometric sequence is \(\Large n > 0\) or \(\Large n \ge 1\) where n is an integer. The reason why is because n is a counting number which indexes the terms n = 1 refers to the first term n = 2 to the second term n = 3 is the third term etc

Best ResponseYou've already chosen the best response.0So then, the answer would be B. Right?

Best ResponseYou've already chosen the best response.1it's NOT b because \(\Large n \ge 0\) includes n = 0 but we don't start with n = 0. We start with n = 1

Best ResponseYou've already chosen the best response.0Oh! Yeah that's true! You dont start w/ ero when you count:)

Best ResponseYou've already chosen the best response.1yeah and when you say "first term" it's natural to think of 1 as the first thing if you made 0 first, then 1 would be second. That's a bit confusing

Best ResponseYou've already chosen the best response.0Hm I didn't think of it like that! But yeah, that's true
