What is the recursive formula and how do we use it

👉 Learn about sequences. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. There are many types of sequence, among which are: arithmetic and geometric sequence.
An arithmetic sequence is a sequence in which each term of the sequence is obtained by adding a pre-determined value, called the common difference, to the preceding term. A geometric sequence is a sequence in which each term of the sequence is obtained by multiplying a pre-determined value, called the common ratio, to the preceding term.

I came here to say thank you for helping me from my geometry class because I passed it with A+ for the whole semesters in my sophomore year and now I’m a senior 😊🙏🏼 I would never forget about this channel

[raimonlewis]

Man you don't know how helpful this is for my summer school, thank you.

[LifewithAmairanny]

Come on Colby I'm trying to focus.

[rutgerhadge]

You are a great math teacher, thanks for making these videos available.

[juliansanciprian]

juss watched the whole thing confused n mad at coby.

[LavenderMoon]

The amount of times this guy has helped me Is actually quite embarrassing, but I’m grateful nonetheless. My district has started this new Carnegie learning math thing and no one is learning anything. I basically have to watch these before my test.

Now I know why I fail bcuz of homework or not paying COBY

A lot of students always get confused by the SUB numbers...the SUB numbers are NOT part of the equation. They are like saying term one, term two, term three....they dont go into ANY of the calculations. At all. Its like saying a Audi8, Audi7, Audi6...they mark a new generation or next years model, Audi 8 doesn't have 8 tires or anything, its just the next years model. But it takes so long to write down term one, term two, term three in words, so we write t1, t2, t3, or a1, a2, a3. The only relationship the sub numbers have is to say a3 comes after a2, and a2 comes after a1, just like models of a car.

its 2020 we’re doing online school u helping me not fail

So this would be for an arithmetic recursive formula, right? And if so do u have a geometric recursive formula example?

[usernope]

f(n+1)=-2f(n)+8 and f(1)= for n>1?
Please help list the first five terms

[EvermoreisTimeless]

Why does Colby have his headphones in...

[altheapalis]

Sir, I have a question, are all explicit formulas arithmetic?

Because my teacher told us to make an explicit formula for this: 2, 4, 7, 11, 16, ... & I think it's supposed to be under recursive..

[onyoucho]

So, can you only find the next term when you're using the recursive formula? I'm confused...

[kelseysanders]

Just trying to clarify wouldn't a4 = 10? Because k=3 and when you plug-in to the formula it would look like this:

a1+1=1^2+1 --> a2=2
a2+1=2^2+1 --> a3=5
a3+1=3^2+1 --> a4=10 *
a4+1=4^2+1 --> a5=17

[edberaga]

I don't know how did the "a3+1 = 5^2 +1".... isn't the k is 3? shouldn't supposed "a3+1 = 3^2 +1"

[clloydmathison]

Either you had a bad headache teaching this topic or you were confused. I love your videos, even though you are just so rushed most of the times. This video should be deleted. It is confusing!!!

[peterlohnes]

Oh coby, you got the old seat change to the front buddy, no more texting in class

[sesameseed]

Well.... u just got a new subscriber lol. Thank you for this!!!

[oofoof]

Instead of “Goddamn it Bobby” it’s “Goddamn it Coby”
