i havent done p6 but proof by induction i think is proving something works with a number, n, then proving it works with the next number n+1 you can say that it will work for all other numbers.

or something like that

Proof by induction:
(1)Assume the statement is true for n = k .
(2) Use this assumption to show that it logically follows that the statement will be true for n = k + 1.
(3) {Important as this step is often omitted}. Show that statement is true for n = 1. => true for all n.
Why not read this in your textbook/class notes ?

Sometimes, but not always, you have to start at n > 1.
For example, prove, by induction that 2^n > n^3. Well this is obviously not true for n=1, or n=2,... It doesn't become true until n=10.
So you have to start by showing that it is true for n=10, then do the n=k and n=k+1 bit

Yes, I should have added that we have to be on the lookout for the domain of n. n is usually a natural number in P6 Edexcel.
