Answer 1

Hi

Answer 2

I canz help ya

Answer 3

Explicit formula means that it you plug in a value for x and you immediately get the answer. Therefore, we know the first term is -2, the second is 8, and so on. There is a common ratio of -4. We multiply each term by -4. Therefore, y=-4x + c. We don't know what c is yet. To find c, we plug in the first term. -2=-4(1) + c. This simplifies to 2=c so c is 2. We then add that back to the original equation. y=-4x + 2. This should be your equation
