Answer

144

The correct answer is 144 — Therefore the 12th term is $144$

Step-by-step solution

Identify the general term as $a_{n} = n^{2}$
Substitute $n = 12$ : $a_{12} = 1 2^{2}$
Calculate $12 \times 12 = 144$
Therefore the 12th term is $144$

Common mistake: Using linear growth instead of quadratic growth
