Given
Power of lens=+1.5D
we know that
Power of the lens=1/Focal length
1.5=1/Focal length
Focal length=1/1.5
Focal length=10/15
Focal length=2/3
Focal length=0.67m
Since the focal length is positive, the lens is convex lens
and the convex lens is converging lens
Hence, the prescribed lens is converging.
