Math help...
 

As you may or may not know I suck at math and am taking Pre-Cal 12 through Corrospondence which equels hard to learn.

-List the first four terms for the following. F(x)=3X + 4, XEN
Not 100% on this. due I graph it and take the first four terms?
same thing but, a1=4,a2=3,an=3avn-1+2avn-2, n>2,nEN. Note v means superscripted.

-Given the sequence
an=2n-1+c/10 (n-1)(n-2)(n-3), given a4=55, what is c? I just plug 55 in for an and 4 in for n right?

-define the first 8 terms of the sequence defined by the recursion formula:
a1=1,a2=1,ak=avk-1+avk-2, k>=3, kEN.

- In a geometricsequence, 4,-2,1: find A10(i can do that) and S(sideways 8 limit thing)if it exists.

- Find all geometric sequences in which T3+T4=36 and T5+T6=144
Found one, an=3+(n-1)2. Is there any others?

Any help is greatly appreciated guys. I owe you.

I hate trying to figure out numenclature from typed shit. So I won't. If you scan the problem and post it, maybe I'll look at it.

Yea, or you could perhaps get a tutor or a classmate to help.

It is hard to understand what you mean but for "
- In a geometricsequence, 4,-2,1: find A10(i can do that) and S(sideways 8 limit thing)if it exists." I think you mean the limit at infinity, which if I'm not mistaken would be 0 (the next value is always -1/2 multiplied by the value of the preceding one, so it would get closer to zero (always twice as close as before), and switch between negative and positive

kinda like that.

There are no classmates through correspondence, the work gets mailed to you and you do it at home. I have to do Math C30(Geo Trig 30) through coresspondence next semester concurrently with Math B30(Algebra 30) it sucks man.

You're still alive? :(

lol yes, why wouldnt I be?
