                200 trees were planted at equal distance apart along the sides of a straight expressway. The
distance between the first and the last tree is 396 m. What is the distance between the first and
the fifteenth tree?

    200 trees means 199 intervals between. So, each interval is 396/199 meters. That means that the nth tree is at a distance from the first of
Tn = (n-1)(396/199)
Now just plug in 15 for n and you have your distance.
    
Tn = (n-1)(396/199)
Now just plug in 15 for n and you have your distance.
