Answer

\(\boxed{\text{The first four terms of the sequence are } a_{1}=0, a_{2}=2, a_{3}=14, \text{ and } a_{4}=590}\)

Steps

Step 1 :The problem asks for the first four terms of the sequence defined by the recurrence relation \(a_{n+1}=3 a_{n}^{2}+2\) with \(a_{1}=0\).

Step 2 :To find these terms, we can start with \(a_{1}\) and use the recurrence relation to find \(a_{2}\), \(a_{3}\), and \(a_{4}\).

Step 3 :Using the recurrence relation, we find that \(a_{2}=3*0^{2}+2=2\), \(a_{3}=3*2^{2}+2=14\), and \(a_{4}=3*14^{2}+2=590\).

Step 4 :\(\boxed{\text{The first four terms of the sequence are } a_{1}=0, a_{2}=2, a_{3}=14, \text{ and } a_{4}=590}\)
