Idk how to this but look up the app Socratic and scan the question it should helped
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
Zero because 60 plus negative 60 equals 0
It is the one in the bottom left corner. This is because you start with the number on the right (7) and plot it on the y axis (the vertical line in the middle). Then you take the slope (3x) and view it as 3/1. Start at 7 and go up 3 and then over one. Continue this until you have a line.
