    Step-by-step explanation:

    let the 4 number be a – 3d , a – d , a + d , a +3 d

    then a – 3d +a – d + a + d + a + 3d=50

    4a=50

    a=25/2

    but a + 3d = 4(a-3d)

    a + 3d = 4a – 12d

    3a=15d

    a=5d

    25/2=5d

    d=5/2

    so the 4 no’s are

    a-3d=25/2-15/2=10/2=5

    a-d=25/2-5/2=20/2=10

    a+d= 25/2+5/2=15

    a+3d= 25/2+15/2=20
