Question 3
In a proof by mathematical induction that 1 + 3 + 5 + ... + (2n - 1) = n^2 for all positive integers n, assuming the result holds for n = k, what expression must be added to k^2 to prove it for n = k + 1?
Correct Answer:
2k + 1
Question 4
When proving by contradiction that sqrt(3) is irrational, we assume sqrt(3) = p/q where p and q are integers with no common factors. Squaring gives p^2 = 3q^2. What is the immediate deduction about p?
Correct Answer:
p is a multiple of 3
Question 5
When proving by induction that 4^n - 1 is divisible by 3 for all positive integers n, if 4^k - 1 = 3m for an integer m, how can 4^(k+1) - 1 be written in terms of m?
Correct Answer:
12m + 3
