    Step-by-step explanation:

    Let the numbers are in AP be a – d, a, a + d

    The sum of the three numbers in A.P. is 27,

    a – d + a + a + d = 27

    3a = 27

    a = 9

    The product of the first and last is 56,

    (a – d)(a + d) = 56

    a2 – d2 = 56

    92 – d2 = 56

    d2 = 81 – 56 = 25

    d = ± 5

    Then the numbers are 4, 9, 14.
