Answer
$(2,6)$ and $(2,-4)$.
Work Step by Step
If the transverse axis is parallel to the y-axis (as it can be seen on the figure), then the y-coordinates of the vertices will be the same as the y-coordinate of the center. We can get the two vertices' y-coordinates by adding and subtracting the given $c$-value from the center's x-coordinate. Hence the 2 foci:
$(2,1+c)=(2,1+5)=(2,6)$ and $(2,1-c)=(2,1−5)=(2,−4)$
