Plz solve this Question!!!The sum of the three numbers in A.P is 21 and the product of their extremes is 45. Find the numbers.

Let the numbers are be a - d, a, a + d

Then a - d + a + a + d = 21

3a = 21

a = 7

and (a - d)(a + d) = 45

a² - d² = 45

d² = 4

d = +2

Hence, the numbers are 5, 7 and 9 when d = 2 and 9, 7 and 5 when d = -2. In both the cases numbers are the same.
