    Let us assume number of n.

    The number is decreased by 15.

    Decreasing by 15 means, we need to subtract 15 from that number.

    So, it would be come n-15.

    Now, it is said that the number would become less than 2.

    So, we need to setup an inequality:

    n-15 is less than 2.

    n-15 < 2 : required inequality.

    Adding 15 on both sides, we get

    n-15+15 < 2+15

    n < 17.

    So, we could say the number would be less than 17.
