please give me the answer:

4. You are given PACF for a stationary process: $11 = -0.60, 422 = 0.36, Okk = 0 for k 2 3. What time series model could have this PACF? Identify model's coefficients and write model equation. Hint: . $6 of Lecture Notes and slides 25-27 of Week 3 provide relationship between PACF and ACF, allowing to calculate ACFs of the model from given PACFs. . Yule- Walker equations, in $4.3 of Lecture Notes and on slide 13, Week 3, provide relationship between ACF and model coefficients
