Module 4: Mathematical Patterns Flashcards
a set of numbers arranged in some order
sequence
ordered arrangement of a set of numbers
sequence
a sequence of values that follows a pattern of adding a fixed amount (always the same) from one term to the next
arithmetic sequence
the fixed amount in the arithmetic sequence is called
common difference
the formula in the arithmetic sequence
an=a1+(n-1)d
a sequence of values that follows a pattern of multiplying a fixed amount from one term to the next
geometric sequence
the fixed amount in the geometric sequence
common ration, r
the formula for finding the common ratio
r= an/an-1
the formula for geometric sequence
an=an-1r or an=a1r^n-1
a means of solving practical problems. sequence is formed by starting with 1,1 and adding the two preceding numbers to get the next number
Fibonacci Sequence
who developed the fibonacci sequence
Leonardo Fibonacci
examples of Fibonacci sequence in nature
nautilus shell, hurricane, galaxy
the ratio of 2 successive Fibonacci numbers approach the number called
Golden Ratio
the golden ratio is irrational and is noted by the ratio of…
(1+√5)/2 approx. 1.618
involves flexible thinking, creativity, judgment, and logical problem-solving.
