WebIn strong induction we show that any (or a combination) of S (k-1), S (k-2)... to S (1) implies S (k+1). If we only use S (k-1) we must verify the first two base cases. If we use S (k-2) we must verify the first three base cases etc. But by definition we must verify at least two base cases otherwise we are using weak induction.

Remarks: Number of base cases: Since the induction step involves the cases n = k and n = k 1, we can carry out this step only for values k 2 (for k = 1, k 1 would be 0 and out of range). This in turn forces us to include the cases n = 1 and n = 2 in the ...
