since the image is formed to the right of the mirror, i.e. it is formed at the backside of the mirror.
Hence it is virtual.
object position, u = -18
image position, v = +4
let focal length be, f
using the mirror equation:
1/v + 1/u = 1/f
thus we can get the value for f
if it is positive, the mirror is convex else it is convex
