1. At least 1 statement among these 2n+1 are true.
2. At least 3 statements among these 2n+1 are false.
3. At least 5 statements among these 2n+1 are true.
2n. At least (4n-1) statments among these 2n+1 are false.
2n+1. At least (4n+1) statements among these 2n+1 are true.
How many statements are true? Which?
(In reply to re: Hypothesis
For n=0, there is only 1 statement:
1) At least 1 statement among this 1 is true.
This can neither be proven true nor false. It is the equivalent of the statement, "This statement is true."
Also, your induction was done incorrectly. Induction has two
steps. First you prove a hypothesis when n=1 (or 0). Next,
you prove that if the hypothesis is true for n=k, it is also true for
The hypothesis you tried to prove seems incorrect. Try other cases with n>1 and you might see a pattern... or not.
