    4 consecutive integers such that the sum of the first 3 integers is equal to the 4th

    Let n be our first consecutive integer.
    1. n
    2. n + 1
    3. n + 2
    4. n + 3
    The sum of the first 3 integers is equal to the 4th:
    n + n + 1 + n + 2 = n + 3

    Simplify by grouping like terms:
    (n + n + n) + (1 + 2) = n + 3
    3n + 3 = n + 3
    3n = n
    n = 0

    n = 0
    n + 1 = 1
    n + 2 = 2
    n + 3 = 3

    Check our work:
    0 + 1 +2 ? 3
    3 = 3

    Our final answer is (0, 1, 2, 3}
