    "when the mystery number is
    divided by 3,there is a remainder
    of 1"

    So, we know that the number must be 1, 4, 7, 10, etc. Each of those numbers n have the property that n modulus 3 = 1. (Modulus is the remainder when a natural number is divided by a natural number).

    "n modulus 4 = 2"
    This limits the numbers to 2, 6, 10, 14, etc. Note that this also means that the number is even.

    "n modulus 5 = 4"
    Similarly, this limits the numbers to 4, 9, 14, 19, etc. The number must be a multiple of 5 with 4 added to it.

    Let us start with the last condition (as it has the greatest increase) and limit it to evens. Find the first number that satisfies the first two conditions.
    4, 14, 24, 34

    34 satisfies all the above conditions.
