What method should i use to know if a recurrence relation is increasing or decreasing?
i was given the following relation:
A1 = 1
An=(An-1)^5 - 3
I know for sure it actually decreases since every term for n>=2 is a negative number raised to and odd number, but i don't know how to demonstrate it mathematically. I tried using induction, but it doesn't work...
Thanks to whoever can answer me.
