Answer:
B
Step-by-step explanation:
For this problem, I basically solved each equation until it agreed with the sequence.
It's not A or C because when you plug in 1, the number doesn't equal 3.
a = 2(-3)¹⁻¹ = 2(-3)⁰ = 2(1) = 0
a = 3(-2)¹ = -6
It's not D because when you plug in 2, the number doesn't equal -6.
a = 3(2)²⁻¹ = 3(2)¹ = 6
