# Best Examples of Mathematical Induction Divisibility

Mathematical Induction Divisibility Proofs Mathematical Induction Divisibility can be used to prove divisibility, such as divisible by 3, 5 etc. Same as Mathematical Induction Fundamentals, hypothesis/assumption is also made at the step 2. Practice Questions of Mathematical Induction Divisibility Basic Mathematical Induction Divisibility Prove $6^n + 4$ is divisible by $5$ [...]

# Mathematical Induction Fundamentals

Mathematical Induction Fundamentals The Mathematical Induction Fundamentals are defined for applying 3 steps, such as step 1 for showing its initial ignite, step 2 for making an assumption, and step 3 for showing it is true based on the assumption. Make sure the Mathematical Induction Fundamentals should be used only when the question asks to [...]

# Best Examples of Mathematical Induction Inequality Proof with Factorials

Mathematical Induction Inequality Proof with Factorials uses one of the properties of factorials, $n! = n(n-1)! = n(n-1)(n-2)!$. Worked Example of Mathematical Induction Inequality Proof with Factorials Prove that $(2n)! > 2^n (n!)^2$ using mathematical induction for $n \ge 2$. Step 1:  Show it is true for $n =2$. [...]

# Mathematical Induction Inequality Proof with Two Initials

Usually, mathematical induction inequality proof requires one initial value, but in some cases, two initials are to be required, such as Fibonacci sequence. In this case, it is required to show two initials are working as the first step of the mathematical induction inequality proof, and two assumptions are to be placed for the third [...]
