If Un<---(suppose to read U sub n) represents the nth term of the Fibonacci sequence show that, Un and Un+1<---(suppose to read U sub n+1) are relatively prime. okay, I dont knoq how to start this, and what exactly does the "sub n and sub n+1" do to the U in this sequence I dont see a relation, because the sequence is 1,1, 2, 3, 5, 8,..., x, y, x+y, etc. How do I show these are prime by using what they are asking.
