Go to Datum curve and select through equation, in equation select cartesian .
paste the below equation,
x=(15+10*t)*cos(360*5*t)
y=(15+10*t)*sin(360*5*t)
z=0
explanation:
x = ( radius + increment * t * nrofturns ) * cos ( t * nrofturns * 360 )
y = ( radius + increment * t * nrofturns ) * sin ( t * nrofturns * 360 )

just use a cylindrical co-ordinate system with theta=n*360 (where n is the number of turns), leave t at 0-1 and r=t
