F1+ F2

as convex lenses are converging lens any light ray parallel to its principal axis will get converged and cut the principal axis at focus...

so the point where the light ray cuts the principal axis is their focal length...

hence the distance between them will be the focal length of one + the focal length of second.

so ans is-

F1+F2
