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.
Notes from Regents Exam Prep: Arithmetic and Geometric Sequences and Series
From Mthcounts Mini:
Easier concepts:
Sequences
Arithmetic sequence/determine the nth term
Arithmetic and geometric sequences
Harder concepts:
Relationship between arithmetic sequences, mean and median
Sequences, series and patterns
From my blog :
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 !!
