7. The autocorrelation function of a random sequence {An} is defined as Ra(m) = E(A$An+m). Suppose that the elements of the sequence {An}- are independent, identically distributed random variables taking on one of three possible values {-1,0, +2} with probabilities P(-1) = 1, P(0) = and P(+2) = . Determine Ra(m).
