Homework Statement
Consider the sequence of real numbers x1, x2, x3,... defi ned by the relations x1 = 1
and xn+1 =[tex]\sqrt{1 + 2xn}[/tex]
1. Use mathematical induction to show that xn+1 > xn
for all n [tex]\geq[/tex] 1.
The Attempt at a Solution
I'm a bit thrown off by this question because it seems very obvious that it would be greater. if x1=1 is it safe to assume that xn=n? and if so I feel like this proof is stupid cause it shows right in front of you that its greater. any help is great thanks.
