I believe the answer is C
Step-by-step explanation:
Answer:
a. an = -1 • 4^(n - 1)
Step-by-step explanation:
It's easy see that each term is multiplied by 4 to get the next term, so the common ratio will be 4, that reduces the choices to answers A and B (since C and D use -1 as common ratio). Also, normally a geometric progression uses "n-1", so we'll first try with A to see if it works.
a1 = (-1) * 4^0 = -1 * 1 = -1
a2 = (-1) * 4^1 = -1 * 4 = -4
a3 = (-1) * 4^2 = -1 * 16 = -16
Yes, it works... so the answer is an = -1 • 4^(n - 1)
J can give you some example:
absolute (1-3)=absolute(-2)=2
Ok so first you know that the missing angle is going to = y+x. Then look at just half to the x so you’re looking at only a “straight line”. That means you are either seeing y+x and 2x together or y-x and y+x together. Either way, both add to 180, so that means they are equal to each other! So, you can set them equal to each other: 2x + y + x = y+ x + y - x. When you simplify that, you get y+3x = 2y so 3x = y. Then you can go back to your first equations, I used 2x + y+x = 180 and where ever there’s a y substitute in 3x. So you are left with 3x + x + 2x = 180 —> 6x = 180 so x = 30°!
