Answer:
Step-by-step explanation:
.let x be the common term and k be the common difference
The three consecutive terms of the sequence are x, x + k, and x + 2k.
sum: 3x + 3k = 21 or x + k = 7 or k = 7 - x
product: x(x + k)(x + 2k) = 315, substitute k = 7 - x
x(7)(14 - x) = 315, divide both sides by 7
