Lesson: 9.1 Sequences
Goals: Write terms of a sequence and simplify factorial expressions
DOD
An infinite sequence is a function whose domain is the set of positive integers.
The function values are the terms of the sequence.
If the domain of the function consists of the first positive integers only, then
the sequence is a finite sequence.
Sometimes we will start at
, and sometimes we will start at
. The
context of the problem will make it clear if we do not start at
.
A recursive sequence is defined by the first couple of terms and how to find the
next term.
Ex. Fibonacci Sequence Factorial
If is a positive integer, is defined by As a special case,
Ex.
