Determine whether each sequence is arithmetic or geometric. Find the next three terms.

1.
14, 19, 24, 29, . . . (1 point)

geometric, 34, 39, 44
arithmetic, 32, 36, 41
arithmetic, 34, 39, 44 ***
The sequence is neither geometric nor arithmetic.

2.
–4, 8, –16, 32, . . . (1 point)

arithmetic, 64, 128, 256
geometric, –64, 128, –256 ***
geometric, –48, 64, –80
The sequence is neither geometric nor arithmetic.

3.
81, 27, 9, 3, . . . (1 point)

arithmetic, 0, –3, –6
geometric, 0, –3, –6
geometric, 1, one-third, one-ninth***
The sequence is neither geometric nor arithmetic.

4. What are the first four terms of an arithmetic sequence if the common difference is 1.5 and the first term is 15? (1 point)

a. 15, 30, 45, 60
b. 15, 16.5, 18, 19.5***
c. 15, 22.5, 33.75, 50.625
d. none of the above

5. What are the first four terms of a geometric sequence if the common ratio is 10 and the first term is 4.5? (1 point)

a. 4.5, .45, .045, .0045
b. 4.5, 9.0, 13.5, 18.0
c. 4.5, 14.5, 24.5, 34.5

#1-4 all ok
#5. What's the trouble? Start with 4.5 and start multiplying by 10's. (D) since you get
4.5 45 450 4500 ...

(a) is common ratio of 0.1

Okay instead of just giving the letters right out the answers. Got it, so I got an 80% with idk whos answers(Thanks whoever was wrong, you made me second guess my answers). I would of gotten a 100 had I not second guessed myself. So here are the right (written) answers. So as of 2019.
1.C- Arithmetic, 34, 39, 44
2.B- Geometric, -64, 128, -256
3.C- Geometric, 1, 1/3, 1/9
4.B- 15, 16.5, 18, 19.5
5.D- None of the above
Here are the right answers as of 2019.

On number 4 for some people its B and for some its C.

as of 2020 is is B- 15,16.5, 18, 19,5
Just add 1.5 to the other number and you will get your answer. Its an arithmetic sequence so you add. The question also tells you what to add so its pretty simple, but I understand how you could get confused.

I hope I helped you. Also, try not to rely to much on this website, because if you do you might fail the STAAR and have to redo your current grade. Use it to check your answers (like me) or to finish the last three questions on an overdue test (like me) but please don't use this to cheat on 100% of your lessons because it will hurt you in the long run.
