Ayo dawg can someone help in due like 5 min??

Answer 1

Answer:

7 stations

19 stations

199 stations

Step-by-step explanation:

We can model the stage number as $x$, and the number of modules as $y$. We can write this as a linear equation, where the initial number of modules is 1, and the number of modules increases by 2 every station. This is $y=2x+1$, but since if you plug in 1 into the equation, you get 3, which is the station number for the next number, you have to edit that into x - 1:

$y=2(x-1)+1$

Expanding, we have 2x - 2 + 1, which is 2x - 1:

$y = 2x - 1$

Now, plugging 4 into the equation, we have 7.

Plugging 10 into the equation, we have 19.

Plugging 100 into the equation, we have 199.
