    Do you mean an arithmetic SERIES?
    (With the accent in the syllable MET?) In that case, "arithmetic" is an adjective with a specific meaning. There are many other kinds of series.

    If so, the difference between consecutive terms must be constant.

    That means that 3x + 5 = 6x - 10
    3x = 15
    x = 5

    The first three terms would be
    5, 25 and 45.
