# If the sum

Let the three numbers in A.P. be a – d, a, and a + d.

According to question -

(a – d) + (a) + (a + d) = 24 … (1)

3a = 24

a = 8

and,

also product of these numbers is 440,

(a – d) a (a + d) = 440 … (2)

(8 – d) (8) (8 + d) = 440

(8 – d) (8 + d) = 55

64 – d2 = 55

d2 = 64 – 55 = 9

d = 3

Therefore,

when d = 3, the numbers are 5, 8, and 11 and

when d = –3, the numbers are 11, 8, and 5.

Thus, the three numbers are 5, 8, and 11.
