The sum of three integers in AP is 15 and their product is 80. The integers are?
-------
1st: a-d
2nd: a
3rd: a+d
--------------
Sum = 3a = 15
a = 5
-----------------
Product: a(a^2-d^2)= 80
-----------------
5(25-d^2) = 80
25-d^2 = 16
d^2 = 9
d = 3
------
1st: 5-3 = 2
2nd: 5
3rd: 5+3 = 8
----------------------
