A pair of speakers connected to the same signal generator face each other, one at x=0 and the other at x=1.5m. If they are producing a sound frequency of 2000Hz what are the points (position x) of constructive interference between the speakers? Express your answer in terms of wavelength

The only equation im given for constructive interference is this
r2-r1=(n+1/2) wavelength

Not sure how to go about this...
