In its not recommended way, you can do the following:

$ awk '/^\\hello$/,/^\\hello2$/{next}1' file

The better, more adaptable way is:

$ awk '/^\\hello$/{f=1}(f==0){print};/^\\hello2$/{f=0}' file

which is reducible too:

$ awk '/^\\hello$/{f=1}!f;/^\\hello2$/{f=0}' file

or see Ed Morton's comment (see below)
