Sequences and Series -- Arithmetic and Geometric Sequences

Sequences are fun to learn and not really that difficult. 
There are many similarities between arithmetic and geometric sequences, so 
learn both together. 

Enjoy !!!!! 

From Mthcounts Mini: Sequences and Series

Easier concepts:

Sequences

Arithmetic sequence/determine the nth term

Arithmetic and geometric sequences

Mathcounts strategies : review some sums 

Note : Don't just memorize, but really understand the concepts.

Harder concepts:

Sum and Average of An Evenly Space

Relationship between arithmetic sequences, mean and median

Sequences, series and patterns

Some Common Sums

This Week's Work : Week 4 -- for Inquisitive Young Mathleges

First of all, problem of the week from Evan, a 5th grader:
A man notices a sign in Shop-a-Lot that says: "All prices are marked 25% off today only!" He decides to buy a shirt that costs $65.12 before the discount. He then uses a $16 gift certificate and the clerk applies 12% sales tax. What is the final cost of the shirt after all the steps are applied? Express your answer to the nearest hundredth. 

This week, we'll learn two very common sequences : arithmetic and geometric sequences.
There are quite a few similarities between these two types and they are closely linked to ratio, proportion
so just watch the videos and play around/generate a few/ponder on those sequences. I don't expect you to learn them in just one week.

Some special arithmetic sequences and the easier way to find their sum

Write some notes of the most important features of the arithmetic sequence.
The best note will be posted here to share with other students.
Be creative !!
