$P$ et
$G$ sont deux points de coordonnées respectivement
$({x}_{P};{y}_{P})$ et
$({x}_{G};{y}_{G})$ dans un repère
$(O,I,J)$.

Quelles sont les coordonnées du milieu du segment $[\mathrm{PG}]$ ?

**Remark.** Choose 'none of the above is correct', if you think that the correct
choice is not among those presented.
