Answer:
Let's assume that three consecutive terms are a-d, a, a+ d.
Given,
Sum of three consecutive terms = 27
Product of three consecutive terms = 504
( a - d) + a + (a + d) = 27
=> 3a = 27
=> a = 9
( a - d) × a × ( a + d) = 504
=> ( 9 - d) × 9 × ( 9 + d) = 504
=> d = +, - 5
When d = 5
The terms are 9,14,19
When d = -5
The terms are 9,4,-1
