The General Term of a Sequence Is Given $$a _ { n } = 3 n ^ { 2 } - 4$$

Multiple Choice

The general term of a sequence is given. Determine whether the given sequence is arithmetic, geometric, or neither. If the sequence is arithmetic, find the common difference; if it is geometric, find the common ratio.
- $$a _ { n } = 3 n ^ { 2 } - 4$$

A) arithmetic, $\mathrm { d } = - 4$
B) geometric, $r = 3$
C) arithmetic, $d = 3$
D) neither
