SWBAT find terms of a sequence given the general term
SWBAT look for a pattern in a sequence and find the general term
SWBAT apply factorial notation
SWBAT apply recursion formulas
An order in which one thing follows another
in succession
In math it’s a function whose domain is a set
of positive integers
Written as 𝑎1 , 𝑎2 , 𝑎3 , … 𝑎𝑛 , …
Finite Sequence: has the domain {1, 2, 3, …, n}
for some positive integer n
Infinite Sequence: has the domain of all
positive integers {1, 2, 3, …}

If n is a positive integer, then n! (stated as “n
factorial”) is the product of all positive
integers from n down to 1
5! = 5 * 4 * 3 * 2 * 1
Evaluate each factorial expression
6!
2!∙3!
9!
7!
3!∙4!
2!∙6!
