HomeWork Help: Count back from the secondary after the last frame? Assume error-free operation..

Q) Assume that the primary HDLC station in NRM has sent six I-frames to a secondary. The primary’s N(S) count was three(011 binary) prior to sending the six frames. If the poll bits are in the sixth frame, what will be the N(R) count back from the secondary after the last frame? Assume error-free operation.
