Best ResponseYou've already chosen the best response.0g goes from 1 to infinity... this is because n  1 > 0 and n is an integer value

Best ResponseYou've already chosen the best response.0well its for a term in an arthimetic sequence where the 1st term is 3 and the common difference is 9

Best ResponseYou've already chosen the best response.2you could have negative subscripts no this is not likely the answer you could have 0 and positive integer subscripts or you could have positive integer subscripts

Best ResponseYou've already chosen the best response.2but what is preventing us from saying \[a_0=3+9(01) \\ a_0=3+9(1)=39=12\] and called the first term 12 instead @campbell_st or mean we could go with negative subscripts as I said before but they are probably not looking for that they are probably looking for what campbell_st said which is n1>=0

Best ResponseYou've already chosen the best response.0I just wouldn't overthink things a term in an arithmetic sequence is \[A_{n} = a_{0} + (n 1) \times d \] so the get the 1st term \[a_{0} ~~~then ~~~n  1 = 0 ~~~solve ~for~n\]

Best ResponseYou've already chosen the best response.2there is no right answer because the sequence can be defined over any integer set but your teacher is probably wanting you to say n>=1 where n is integer
