1. In a proof by strong mathematical induction the basis step may require
|
||||
checking a property $P(n)$ for more _____ value of $n$.
|
||||
|
||||
than one
|
||||
|
||||
2. Suppose that in the basis step for a proof by strong mathematical induction
|
||||
the property $P(n)$ was checked for every integer $n$ from $a$ through $b$.
|
||||
Then in the inductive step one assumes that for any integer $k \geq b$, the
|
||||
property $P(n)$ is true for all values of $i$ from _____ through _____ and
|
||||
one shows that _____ is true.
|
||||
|
||||
$a$; $k$; $P(k + 1)$
|
||||
|
||||
3. According to the well-ordering principle for the integers, if a set $S$ of
|
||||
integers contains at least _____ and if there is some integer that is less
|
||||
than or equal to every _____, then _____.
|
||||
|
||||
one integer; integer in $S$; $S$ contains a least element.
