Section 3.2.1 says:

This field is initialized at a random number and incrementedmonotonically for each packet of the session flow of the5-tuple.  The random-number initialization is intended to makeit harder to spoof and insert such packets.

It should say:

This field is initialized at a random number and incrementedsequentially for each packet of the session flow of the5-tuple.  The random-number initialization is intended to makeit harder to spoof and insert such packets.

Notes:

The term monotonically increasing just means that the value must not decrease; it does not mean that it must increase. For example a monotonically increasing sequence may be: 1,2,2,2,2,2,2,2. On the other hand, a sequentially increasing example would be 1,2,3,4,5,6,7,8. I believe that the authors intended for the value to increase sequentially for each packet.
