N n n1 2. Just replace n by k. Since there is no starting point no first domino as it were then induction fails just as we knew it ought to.
The technique involves two steps to prove a statement as stated below Step 1 Base step It proves that a statement is true for the initial value.
Since there is no starting point no first domino as it were then induction fails just as we knew it ought to. More formally you can think of it as a series of 3 standard induction proofs. Show it is true for the first one. Mathematical Induction is a special way of proving things.
