What does it mean to identify hybrid orbitals in problem 4.35?

After drawing the lewis structures, it asks you to find the hybrid orbitals, which you can find by finding out the number of atoms bonded to the atom + the number of lone pairs the atom has.

BF3 has three bonds and no lone pairs. There is a total of 3 bonds, which is trigonal. The hybrid orbital is sp2.
AsF3 has 3 bonds and one lone pair. There is a total of 4 bonds, which is tetrahedral. The hybrid orbital is sp3.
BrF3 has 3 bonds and two lone pairs. There is a total of 5 bonds, which is trigonal bipyramidal. The hybrid orbital is dsp3.
Lastly, SeF3+ is also tetrahedral; sp3 is the hybrid orbital.
