Question

Please check my work?

Given the arithmetic sequence an = 4 − 3(n − 1), what is the domain for n?

All integers where n ≥ 1 <--- (My Choice)
All integers where n > 1
All integers where n ≤ 4
All integers where n ≥ 4

If I am wrong, can I please get some help? Thanks

i am going to guess that your choice is right, but honestly the domain could be anything you say it is 
the domain is something you declare, not something you find

Okay, thank you. And I am aware some of these questions are worded oddly.

anonymous · Answer

it is not worded oddly, it is straight up wrong
you could say "the arithmetic sequence $a_n=4+3(n-1)$ for $n\geq 10
$ and it would be a perfectly good arithmetic sequence
another example for my "bad math" folder
