Intermediate I Patterns, Relations, Algebra, and Time (3-4 new curriculum) Flashcards
can indicate position in a sequence
ordinal numbers
What is the name for a sequence that has a definite end?
finite sequence
e.g. a countdown
A list of terms arranged in a certain order
sequence
What is the name for a sequence that does not end?
infinite sequence
even numbers
the infinite sequence of integers which are multiples of 2
odd numbers
the infinite sequence of integers which are not divisible by 2
How could you determine a missing term in a skip-counting sequence?
add from the last term according to the pattern you see
multiply the spot number by the “added number”
arithmetic sequence
uses addition or subtraction to get to the next term in the sequence
e.g. skip counting sequences are arithmetic
geometric sequence
uses multiplication or division to get to the next term in the sequence
It has a constant multiplicative change between consecutive terms
e.g. 1, 5, 25, 125 …
note: also gives us an exponential graph (you will learn about this later)
Fibonacci sequence
Created by adding the last two terms together to get the next term
0, 1, 1, 2, 3, 5, 8, 13, …
initial term
the first number in a sequence
constant change
the amount that you must add to the term to get the next term
note: also known as slope of the line in later years, giving a linear relation
Example of a base 60 system
clock
basic unit of time
second (s)
How many seconds are in a minute?
60
