We know that a1 = -1, and an = 2 * an-1.
We already know that the first time, a1, is -1. We're given the formula to find the next terms in the sequence.
For a given term in this sequence, it will be 2 times the last item in the sequence.
an = 2 * an-1
a2 = 2 * a2-1 = 2 * a1 = 2 * -1 = -2
a3 = 2 * a3-1 = 2 * a2 = 2 * -2 = -4
a4 = 2 * a4-1 = 2 * a3 = 2 * -4 = -8
a5 = 2 * a5-1 = 2 * a4 = 2 * -8 = -16
a6 = 2 * a6-1 = 2 * a5 = 2 * -16 = -32
Answer:
<h2>
N=-2</h2>
Step-by-step explanation:
Step 1: Subtract 1 from both sides.
2n+1−1=−3−1
2n=−4
Step 2: Divide both sides by 2.
2n/2=−4/2
n=−2

(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
The answer is 60 because 2x3 is 6 so 20x 3 is 60
I would say the ratio would 5:30 which is 5 to 30 ratio, since there are five cards you can grab that would work.
hope this helps
