Question
Use induction to prove: for any integer n > 1,
3|(n – 4n + 6).
-
Hint: this question is case sensitive, you should
ONLY use k, but not K in your answers.
Base case
n =
, n? – 4n + 6 =
which is
divisible by 3.
Inductive step
Assume that for any k >
, 3|
, we will prove that 3|
By the inductive hypothesis, there exists an integer m
such that
= 3m. It follows that
k3 :
(k + 1)3 – 4(k + 1) + 6 =
k³+
k²+
k+
By inductive
hypothesis
= 3(
Since m and k are integers,
must be an integer. Hence,
3|
