Prove through induction that $3^n > n^3$ for $n \\geq 4$
You get your induction started by checking that $a_{n_0}>b_{n_0}$. For the induction step there are two very natural things to try. Compare $a_{k+1}-a_k$ with $b_{k+1}-b_k$: if $a_k>b_k$ …
Prove by Induction: $8^n - 3^n$ is divisible by $5$ for all $n …
2015年9月6日 · Step 1: For $n=1$ we have $8^1 - 3^1 = 8 - 3 = 5$ which is divisible by 5. Step 2: Suppose (*) is true for some $n=k\geq 1$ that is $8^k-3^k$ is divisible by 5. Step 3: Prove that …

Prove that $8^n - 3^n$ is a multiple of 5 by mathematical
Since both forms in this sum are multiples of 5 (the first because it is 5 times an integer and the second by the assumption of the induction step), it follows that $8^{k+1} - 3^{k+1}$ is also …
