Answer:
50,70,90
Step-by-step explanation:
Let the numbers be a, a+d , a-d
Sum of the numbers,
a+a+d+a-d = 210
3a = 210
a = 70
again,
a(a+d) (a-d) = 315000
( a²-d²) a = 315000
70²* 70 - d²70 = 315000
343000- 70d² = 315000
70d² = 343000 - 315000 = 28000
d² = 400
d = 20
therefore the numbers are,
a = 70
a+d = 70+20= 90
a-d = 70-20 = 50
