I'm kind of confused by this post. Here's my understanding of induction, Your proving that it's true for when n = 2, then your assuming it's true for any number n, then you have to prove that if n is true, then n + 1 is true, and so on. Your basically proving that it's true for all n > 1...

Thank's a lot for your help Mark, you really steered me in the right direction here. I proved that when n=2 the sum was rational using a/b + c/d etc etc etc, but after i assume that when n=n , for all natural numbers the sum is rational, isn't that as far as you'd think i would have to go? I...

Homework Statement Prove via Mathematical Induction that, The sum of n rational numbers is rational. Homework Equations The Attempt at a Solution Let N = 1 The sum of one rational number is the number it's self, which is a rational number. Assume when n = n, the sum of n...

Ooo.. Thanks man :) But how do i use the equation when they only give that much information, i am lost :( But i do understand your point.

Thank's. So how do i do the question?

Somebody please help me ! :(
