Carbon number 4 is a pseudo chiral center because its chirality depends on the chirality of the second and sixth carbons. For example, if the second carbon is S and the sixth carbon is R, then carbon number 4 can be r or s, but if the chirality of the second and sixth carbons are the same, then carbon number 4 is not the chiral center, because it doesn't have 4 different groups around itself.

When C2/C6 are of different configurations (R/S), C4 will be stereogenic and achirotopic (r/s). When C2/C6 are of the same configurations (R/R or S/S), C4 will be chirotopic and non-stereogenic. There is no r/s assignment. See: More

Pseudoassymetric center is the carbon that show chirality and achirality simultaneously.
The r/s (not R/S) nomenclature of carbon 4 depend on R/S configuration of directly attached carbon atom.
In the given molecule the carbon 4 is attached with constituitionaly same but configurationaly different group so it is a chiral center (note: R configuration has priority over S configuration). if we imagine it has a plane of symmetry and that make it achiral.
