Question and answer in screenshot, PLEASE HELP!

Answer 1

Look at the numbers for N.
3, 9, 27, 81, etc.
How do you go from one number to the next?

Answer 2

You multiply by 3

Answer 4

Do you know how to do PEMDAS and Properties of Equality and exponents?

Answer 5

@lilkg77 : It make take me a little while to answer each question because I'm kinda busy helping out my parents.

Answer 6

The answer is D.

To truly understand how this equation works, well, you have to experiment.
For this, I decided to put N=3 because it’s week 1.
The exponent in front of (3) is w (which stands for week), and fill it in as 1.
The subtraction of exponents to exponents is same as constants minus constants (constants are # that do not have variables in front of them).
1-1 is 0.
(3) to the zero power is 1. Any number to the power of 0 is 1. 3 times 1 is 3!
So N=3.

Hope this helps!

Thanks @GeniousCreation

Answer 8

That is correct. Each number, N, is 3 times the previous number.
A sequence that multiplies the previous number by a constant amount, in this case, 3, is a geometric sequence.
Start with 3.
Then you have 3 * 3 = 3^2
Then you have (3 * 3) * 3 = 3^3
Then (3 * 3 * 3) * 3 = 3^4
You need to find a function in the choices that starts at 3 and always multiplies the previous value by 3.

Answer 9

No problem.
