Given the geometric sequence where a1 = 2 and the common ratio is 4, what is the domain for n? the answer should be all integers where n is greater than or equal to 1. at least that's what i got. edit, i had to turn it in, so i found out the answer. it actually is the above answer. this is like the first time i got something right haha

Sequences are usually defined as a function with a domain in the set of positive integers. the terms of the sequence are usually denoted as  ,  ,    . it is defined the way it is so that the "first" term would correspond to n = 1, the "second" term would correspond to n = 2, and so on.  these would be based on the apparent terms, terms enumerated based on what we see.that is the gist of why the answer is "all integers where n  ≥ 1"we do not include "0" because there is not a zeroth term when we are relying on apparent terms
