Use strong induction to show that every positive integer can be written as a sum of distinct powers of two (i.e., 20 = 1; 21 = 2; 22 =4; 23 = 8; 24 = 16; :). For example: 19 = 16 + 2 + 1 = 2^4 + 2^1 + 2^0 Hint: For the inductive step, separately consider the case where k +1 is even and where it is odd. When it is even, note that (k + 1)=2 is...

4. Let P(n) be the statement that a postage of n cents can be formed using just 4-cent stamps and 7-cent stamps. The parts of this exercise outline a strong induction proof that P (n) is true forn > 18. a) Show statements P(18), P(19), P (20), and P(21) are true, completing the basis step of the proof. b) What is the inductive hypothesis of the proof? c) What do you need to prove in the inductive step? d) Complete...

11: I can identify the predicate being used in a proof by mathematical induction and use it to set up a framework of assumptions and conclusions for an induction proof. Below are three statements that can be proven by induction. You do not need to prove these statements! For each one clearly state the predicate involved; state what you would need to prove in the base case; clearly state the induction hypothesis in terms of the language of the proposition...

6. Prove by strong induction: Any amount of past be made using S 7 and 13 cent stamps. (Fill in the blank with the smallest number that makes the statement true). Let fib(n) denote the nth Fibonacci number, so fib(0) - 1, fib(1) - 1, fib(2) -1, fib(3) = 2, fib(4) – 3 and so on. Prove by induction that 3 divides fib(4n) for any nonnegative integer n. Hint for the inductive step:...

4.4.3. Proposition. Every sequence of real numbers has a monotone subsequence. strictly Proof. Exercise. Hint. A definition may be helpful. Say that a term am of a sequence in R is a peak term if it is greater than or equal to every succeeding term (that is, if am ≥ am+k for all k ∈ N). There are only two possibilities: either there is a subsequence of the sequence (an) consisting of peak terms, or else there is a last...

In the following problem, we will work through a proof of an
important theorem of arithmetic. Your job will be to read the proof
carefully and answer some questions about the argument. Theorem
(The Division Algorithm). For any integer n ≥ 0, and for any
positive integer m, there exist integers d and r such that n = dm +
r and 0 ≤ r < m. Proof: (By strong induction on the variable n.)
Let m be an arbitrary...
