The sequence is defined recursively. Write the first four terms.
-$a _ { 1 } = 3$ and $a _ { n } = 2 a _ { n - 1 }$ for $n \geq 2$
A) $3,5,4,3$
B) $3,6,12,24$
C) $3,8,14,26$
D) $4,8,16,32$

The sequence starts with $a_1 = 3$. Each subsequent term is twice the previous one. So, $a_2 = 2 \times 3 = 6$, $a_3 = 2 \times 6 = 12$, and $a_4 = 2 \times 12 = 24$.

The Sequence Is Defined Recursively a1=3a _ { 1 } = 3a1​=3

The Sequence Is Defined Recursively $a _ { 1 } = 3$
