Answer:

You add by 5, then 15, then 45 and so on

Step-by-step explanation:

First, you add 5, then you add 15, then you add 45 and so on. You are multiplying 3 and 5 every-time. I don't really know how to explain it but ya.

To get from 3 to 8, add 5. To get from 8 to 23, add 15. You're multiplying by 3 for every number. (I'm super bad at explaining)

Answer: Add the number previously added multiplied by 3;

+3x, where x is the number that was added previously

Step-by-step explanation:

3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.

Ad libitum [116K]

Answer: B.  |x-100| = 25

Explanation:

Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.

The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
