Answer:
$191.59
Step-by-step explanation:
Your answer is the second option, -3, -6, -12, etc.
The information we are given tells us that a1 = -3 and an = 2 × a(n - 1). This means that if we want to find the value of a2, we just need to substitute -3 into the equation:
a2 = 2 × a1 = 2 × -3 = -6
And then to find a3, we substitute in a2, which in this case is -6, so:
a3 = 2 × a2 = 2 × -6 = -12
The only option with the first 3 terms as -3, -6, -12 is the second option, so that is the answer.
I hope this helps!
