Answer 4

1. I do not know. Are you finding three terms, before the 30 in the sequence? -(This would be: 54, 46,38) Or, are you finding the next three terms of the sequence? -(This would be: -2, -10, -18)

2. It is basically multiplying each term by 2 to get the next term.

2 x 4 = 8
2 x 8 = 16
2 x 16 = 32

3. Correct.

4. Correct.

5. I do not know. I may work on this one more.

I hope this helps? :)

P.S. Please be more patient in the future, and please try to not do things with a timer. Timed things just don't work well on this site, so please stick with non-timed things for this website. I am just trying to give you some tips that I have learned from posting on this website.

Well, technically. It's the systems/teachers fault for making things so difficult.
This is like high school stuff, and half you will never use. They just use this as an excuse to keep you in school longer then you have to.

Lesson 10: Patterns and Rules Unit Test
Math 7B Unit 3: Patterns and Rules

20. ESSAY: Easiest to put it, but explain more in your own words: look at b: each increase is 0.8. You can take 4.6-3.8 and you get 0.8. You can go from there.

21. ESSAY: Again, put in your own words. Look at each point. Rita rode faster at each point. At the final point, the 8 blocks, Rita also rode faster. Rita ended up riding her bike at an average of 1 minute per block. (8 blocks in 8 minutes) When Juan rode his bike at an average of 2 minutes per block. (8 blocks in 16 minutes)
