Last class we worked on some slides about interpolation and extrapolation.

Then we worked on some sequences, we went into some small groups.

Arithmetic Sequence:

- Recursive Definition:

An ordered list of numbers generated by adding a value continuously.

{/EDIT} An arithmetic sequence is when you continue adding the same number over and over again. For example:

5, 10, 15, 20, 25...

That is adding five to the previous number.

And to find the equation of the numbers the formula is Y = ax + b, so it would be like, Y = 5x + 0 (used the sequence above for example).

If you're wonder how i got the zero, look at slide 8/13 for December 18th.

It's pretty much just subtracting 5 from 5 because a = the first term and you subtract 5 from the first term.

Since the sequence is just adding 5, the common difference is 5, because there's a difference of 5 in each of the numbers.

I hope this is enough =)

sorry guys, i have no idea what im doing =.=''

Hi Sandra,

You got off to a good start by noting the topics for class!

Will the slides that Mr. K. posted help you? Don't they assist with examples and definitions and problems?

Can you use a problem from them and explain what you did to reach the answer?

I'm thinking that would help your classmates and me--too!

Best,

Lani
