## joyflow 2 years ago PLZ HELP MEDAL WILL BE GIVEN 1)Give the next two numbers in this sequence: 2, 5, 8, 11, ___, ___ 2)Give the 50th number in the sequence. You must show your work. 3)Write an equation to describe this sequence. You must show your work. 4)create a new problem on sequences and give a complete explanation for the answer.

1. Emah

The first one, each number is increasing by 3... I had a huge thing written out then ralized it didn't even make sense to me so I deleted it haha..

2. joyflow

lol funny

3. Emah

Sorry bro.... maybe you could tag someone you know thats smart

4. Emah

@precal

5. Goten77

wouldnt this sequence just be 3x + 2 .. .then that gives u the number at any of them?

6. Goten77

3x+2

7. Edutopia

8. Edutopia

starting with the zeroth term

9. joyflow

3x+2 and i can use tht for all of them?

10. Edutopia

you would plug in 49 for the 50th term though

11. joyflow

ok, thanxs can yu help me wit the others?

12. Edutopia

all you have left is number 4, so for that think of a linear equation and write it as a progression

13. Edutopia

i should say, write out the y values for the corresponding x = {1,2,3 ... n-1, n} as a progression

14. Edutopia

so if you choose 2x + 1, then for x = {0,1,2,3} you would write the progression y = {1,3,5,7}

15. joyflow

ok thanxs

16. Edutopia

does that make sense? your just plugging in values, y is just x augmented by a function (in this case 3x + 2)

17. joyflow

umm ithink i got it, not sure tho

18. Edutopia

i can walk you though it if you want

19. joyflow

sure

20. Edutopia

a progression is just a sequence of numbers with equal spacing, like 0,1,2,3,4 is each term plus 1

21. Edutopia

thinkk of this as your x axis, 0,1,2,3...exc,

22. Edutopia

what a function does is takes this progression and relates it to another progression, 3x for example is a function that takes each number on your x axis and multiplies it by three

23. Edutopia

so your second progression, think of it as your y axis, is really just the x axis multiplied by three

24. joyflow

ok
