State whether the following proof (by mathematical induction) is true or false for the statement.
P(n): 12 + 22 + ... + n2 =(n(n+1)(2n+1))/6
By the Principle of Mathematical induction, P(n) is true for n = 1,
Again for some k ≥ 1,
Now we prove that
Solution False
Since in the inductive step both the inductive hypothesis and what is to be proved are wrong.
