Given the arithmetic sequence an=2-5(n+1), what is the domain for n? My answer choices are: all real numbers
All integers where n is greater than or equal to 1
All integers where n1
Or all integers where n2

I think it's all real numbers, but n can't be a fraction so I'm not sure. I think it might be all integers. Where in is greater than or equal to 1. I just want to check.

it is defined for all real numbers so domain is all real numbers.
There is no restriction.
