Let x0,a,b be reals given such that b>0 and x0=0. For every nonnegative integer n a real value xn+1 is chosen that satisfies xn+12=axnxn+1+bxn2.
a) Find how many different values xn can take.
b) Find the sum of all possible values of xn with repetitions as a function of n,x0,a,b. recurrence relationalgebra
