Can You Please Help Me With A Precalc Question!!! (10 Points)?

Given: Sn=(n^2)+3, where Sn is sum of the sequence
Find: first 5 terms of the sequence
And it doesnt say if the sequence is arithmetic or not. Also could you give answers with explanations, please.
And i was also thinking of just pluging in numbers like 1, 2, 3, … but then i thought that n^2+3 is sum and not an Nth term formula, and it seems too easy that way anyway xD
Thank you in advance
