| Question 890404:  Three intergers are in A.P. The difference between first and last terms is 4 and their product is 60. what are the integers
 Answer by CubeyThePenguin(3113)
      (Show Source): 
You can put this solution on YOUR website! AP = arithmetic progression a = first term
 d = common difference
 
 a, a+d, a+2d
 
 (a+2d) - a = 4 ---> d = 4/2 = 2
 
 a(a+4) = 60
 a^2 + 4a - 60 = 0
 (a + 10)(a - 6) = 0
 
 The integers could be {-10, -8, -6} or {6, 8, 10.}
