    Let us assume the first number = x

    Then

    The second number = x + 1

    The third number = x + 2

    The fourth number = x + 3

    Then we can write the equation as

    x + x + 1 + x + 2 + x + 3 = 40

    4x + 6 = 40

    4x = 40 - 6

    4x = 34

    x = 34/4

    = 17/2

    Then

    The second number = x + 1

    = (17/2) + 1

    = (17 + 2) / 2

    = 19/2

    So the second consecutive number is 19/2
