Prove the following theorem: For every integer n, there is an even integer k such that

n ≤ k+1 < n + 2.

Your proof must be succinct and cannot contain more than 60 words, with equations or inequalities counting as one word. Type your proof into the answer box. If you need to use the less than or equal symbol, you can type it as <= or ≤, but the proof can be completed without it.

Prove that there is no positive integer n so that 25 < n^2 < 36. Prove this by directly proving the negation.Your proof must only use integers, inequalities and elementary logic. You may use that inequalities are preserved by adding a number on both sides,or by multiplying both sides by a positive number. You cannot use the square root function. Do not write a proof by contradiction.

Prove the following statement by mathematical induction. For every integer n ≥ 0, 2n <(n + 2)! Proof (by mathematical induction): Let P(n) be the inequality 2n < (n + 2)!. We will show that P(n) is true for every integer n ≥ 0. Show that P(0) is true: Before simplifying, the left-hand side of P(0) is _______ and the right-hand side is ______ . The fact that the statement is true can be deduced from that fact that 20...
