Front of worksheet - http://s1274.beta.photobucket.com/user/hmp311/media/79DD36AF-4F70-4784-97B5-226A6C409C26-1004-0000027E6A8A60EF_zps090e1c10.jpg.html?sort=3&o=0 Back of worksheet: http://s1274.beta.photobucket.com/user/hmp311/media/DA94FDCA-12B4-4277-83C3-DC247356D86F-1004-0000027D54B7A7B3_zpsca1cd822.jpg.html?sort=3&o=1 (Note: I am to do the odds only - ex. problem 1,3,5....) Thanks

OpenStudy (anonymous):

please help?

OpenStudy (anonymous):

whatever @CliffSedge is writing, just know that i give him/her a medal :P

OpenStudy (anonymous):

Ok, first look to see how each term follows from the previous one. e.g. 1) -7, -10, -13, -16, ... It seems like each term is 3 less than the one that came before it, so follow that pattern.

OpenStudy (anonymous):

k yummydum

OpenStudy (anonymous):

*blushes*

OpenStudy (anonymous):

lol cliff

OpenStudy (anonymous):

okay,let me take a look

OpenStudy (anonymous):

I love you guys. ;-)

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

so, -19?

OpenStudy (anonymous):

would that be the first blank on number one?

OpenStudy (anonymous):

done

OpenStudy (anonymous):

so i got -19,-22,-25,-28 on no.1

OpenStudy (anonymous):

Looks good.

OpenStudy (anonymous):

Yay. Onto no.2 Okay, so i try, you check?

OpenStudy (anonymous):

i mean 3

OpenStudy (anonymous):

-1.25,-1 for the first two?

OpenStudy (anonymous):

Are those numbers negative? I can't read the picture so well.

OpenStudy (anonymous):

it is 0.25,0.5,0.75,1..

OpenStudy (anonymous):

cliff?

OpenStudy (anonymous):

Yep, so keep going with that pattern.

OpenStudy (anonymous):

ok

OpenStudy (saifoo.khan):

Which problem do youn eed help with?

OpenStudy (anonymous):

number 9

OpenStudy (anonymous):

the odds.

OpenStudy (saifoo.khan):

Solve step by step: Let's insert 1 first. y = 3(1) - 1 y = 2 So first term = 2 Insert 2. y = 3(2) -1 y = 5 And so on..

OpenStudy (anonymous):

um it says which one fit the sequence

OpenStudy (saifoo.khan):

Yes.. so we are going to try insert the values 1,2, 3, 4 and so on..

OpenStudy (anonymous):

Ok ill try. i do not get jt

OpenStudy (saifoo.khan):

Why? Where are you stuck?

OpenStudy (anonymous):

Well, you want me to insert the numbers in each answer choice into the equation

OpenStudy (saifoo.khan):

No. Okay. Let me explain you again. Forget everything now

OpenStudy (anonymous):

okay

OpenStudy (saifoo.khan):

Step 1: Forget that you are given any options. Step 2: You are given an equation. y = 3n -1 Where the value of indicates the term number.. 1, 2, 3, and so on..

OpenStudy (anonymous):

yes

OpenStudy (saifoo.khan):

Alright, so now: y = 3n - 1 Find the first term: y = 3(1) - 1 y = 2 So first term = 2 ---------------------- Find 2nd term Insert 2. y = 3(2) -1 y = 5 Now find 3rd term

OpenStudy (anonymous):

the thirdnterm would be 8?

OpenStudy (saifoo.khan):

Perfect.

OpenStudy (saifoo.khan):

Now look at your options

OpenStudy (anonymous):

c:0

OpenStudy (anonymous):

thanks!

OpenStudy (anonymous):

OpenStudy (saifoo.khan):

I can see that each term increases with 0.25. Agree?

OpenStudy (anonymous):

Umm no13?

OpenStudy (saifoo.khan):

yes

OpenStudy (anonymous):

from 2 to 3 it is .25? oh.ok

OpenStudy (saifoo.khan):

Yup. So the equation will look like. 0.25n

OpenStudy (anonymous):
