    There are to types of sequence, an arithmetic sequence and geometric sequence. an arithmetic sequence has a common difference, while a geometric sequence has common ratio.

    fist let us try if they have a common difference

    D = a2 - a1 = (13 4/5) - (14 3/10) = - 1 / 2

    D = a3 - a2 = (13 3/10) - (13 4/5) = - 1 / 2

    so they have a common difference then it is a arithmetic sequence
