Find the nth term rule for ascending quadratic sequences in the form ax² + bx + c \(
6,14,28,48,74, \ldots
\)

When calculating the nth-term rule of this sequence, what should replace the triangle?

nth-term rule: \( 3 n^{2} \)\( \color{red}\triangle \)  \(n\) \( \color{purple}\square \)
 \[
+1
\]
(or just a + sign)
