Given a sequence:
1,12,13,14,15,...
Its explicit formula can be given as:
a(n)=1na(n)=1n where n≥1n≥1.
I actually want to know is it a geometric sequence or an arithmetic one?
I tried finding common ratio and the common difference in this sequence to see if it's either one of them but was not successful.
My common ratio (rr) and common difference (dd) were some horrible values.
