Working out Bond Enthalpy from a Born Haber cycle?

How would you find the value of a F-F bond from this data? I've drawn a correct cycle out but the calculation doesn't make sense to me. My teacher missed this part out of our lessons so any help would be appreciated :-) It is in context of AgF.

Enthalpy change Value / kJ mol–1
Enthalpy of atomisation for silver +289
First ionisation energy for silver +732
Electron affinity for fluorine –348
Experimental enthalpy of lattice dissociation for silver fluoride +955
Enthalpy of formation for silver fluoride –203

The silver fluoride Born Haber cycle is fundamentally the same as the sodium chloride cycle, to which I am linking you ...
