2 points) Consider the sequence X+ = (ai + bi–1)2-; ,t = 1, 2,..., j=1 where {Zt} is a sequence of i.i.d. random variables with mean 0 and variance oz and 0 < a, b < 1. Evaluate x(2). You have to evaluate completely the geometric series.

) Zt-j tol Consider the sequence Xt = E la't but I ไ j=1 where {zty is sequence of ind random variables with mean o and variance 62 and oca, b<1. Evaluate racz). bc1 levaluace completely geometric series)
