I would immediately crank out a few terms . . .
We have an arithmetic sequence: first term 1, common difference 3.
The general term is: .
Thanks Soroban! However, I was wondering if
dn = d1 (subscript didnt work)
Since 1 is the first term and the common difference is 3, do we simply say 4-1
How do we get dn = 3n-2, is really what Im asking?
How do I do subscripts so they will show up here?
