The trick used in mathematical induction is to prove the first statement in the sequence, and then prove that if any particular statement is true, then the one after it is also true. This enables us to conclude that all the statements are true.

WebbBy induction, we know that the statement A(n) given by P n j=1 (2j 1) = n2 is indeed true for all n 1. A common mistake in induction proofs occurs during the inductive step. Frequently, a student wishing to show that A(k + 1) is true will simply begin with the statement A(k + 1) and then proceed logically until a true statement is reached.

WebbUsing the definitions for an empty sum or an empty product allows for this case. For instance, X x∈∅ x2 = 0. That is, the sum of the squares of the elements of the empty set is 0.
