Wikipedia:Articles for deletion/Three forms of mathematical induction
as the selection of the three forms is .  (This is an oddity, as I see it.  All of the article could be merged into different articles.)  My suggestion would be to find a good name for the 2nd form, and keep that as a separate article, merging all the rest into Mathematical induction.  Specifically -- forms 1 and 2 are the same '''type''' of induction, with the difficulties in different steps, while form 3 is '''different'''.  They should not all be in the same article without including a number of of still different forms.  Furthermore, the triangle inquality miscounts "n".  The step that is impossible is '''2''' to '''3''', rather than '''1''' to '''2''', as the trivial equation is d \left( x_1,x_1 \right) \leq 0.  (In other words, I agree with
