Suppose that, you want to send $6$ packets back to back using TCP$.$ The size of the packets is $10$ bytes, $25$ bytes, $35$ bytes, $10$ bytes, $35$ bytes, and $22$ bytes, respectively. Suppose that, the initial sequence number is P$.$ Here, the ACK of the $3$rd packet will be lost and the $5$th packet will be lost. What will be the final ACK number after sending all of the above $6$ packets? Explain using the proper diagram.

Here, P $=015$
