THE GENERAL CONCEPT OF A SEQUENCE 7 A geometric sequence has the form a,ar,ar2,ar3. I hardly had the heart to tell them they had been manipulated. The distinguishing feature of an arithmetic sequence is that each term is the arithmetic mean of its neighbors, i.e. I’ve had classes wonder how they missed it the first time. It’s the same video as before, without the part where she says how many push ups Bucky did edited out. Once they are there, give them: TD, FG, TD, TD, TD, TD, TD, TD, TD, FG, TD, TD, TD.Įxtensions: Does it matter where the two field goals occur? Where would we put the two field goals so that Bucky ends up doing the most possible push ups? University of Minnesota Geometric Sequences and Series.
#Sequences and series activity series
The cards are organized as follows: Cards 1-6: Arithmetic Sequences Cards 7-12: Arithmetic Series Cards 13-28: Geometric Sequences Cards 19-24: Geometric Series. Geometric Sequences A geometric sequence is a sequence of numbers in which the recursion is to multiply by a constant, called the common ratio. Sequences and Series Task Cards ( Arithmetic & Geometric)Students will practice solving sequences and series problems through these 36 task cards. If they don’t think the order of the scoring matters, don’t give it to them. University of Minnesota Geometric Sequences and Series. Then if they score a touchdown, Bucky does 17 push-ups, because their score is now 17, bringing his push-up total to 34.Īsk students what further information they required. Many sequences have patterns and through these patterns, you will be able to identify the different. At this point he has done 17 push-ups in total. a series represents the sum of the terms of a sequence. Learning Targets: Determine whether a given sequence is geometric.
If they follow that up with a field goal, he does 10 push-ups, because their score is now 10. A growing patterns of squares or triangles formed from toothpicks is often used to show linear sequences in a. If Wisconsin scores a touchdown, he does 7 push-ups because their score is now 7. Sequences can be derived from shapes and patterns. Any time I’ve used this, students wonder how many push ups Bucky had to do. Use the calculator to generate the formula for a Geometric Series Gain an understanding of Geometric Sequences and Series through powerful visuals. You are viewing quiz Quiz 9 in chapter 26 of the course: College Algebra: Help and Review Course Practice. I tried this with great success in a Math 10-4 class once.Īsk them what they wondered about. Generation of a geometric sequence and series using Sigma notation. Sequences and Series: Help and Review Status: Not Started. It’s an easy problem at the 20-1 level, so the message to students is that sometimes a formula makes these kind of calculations more efficient.
I like to use this one as an introduction to sequences and series in Math 20-1.
