    The first term of an arithmetic sequence is 10 and its common difference is

    negative seven. What is the fourth term of the sequence?

    The fourth term is - 11

    Explanation:

    a. p = a1 + (n-1) d

    a. p = 10 + (4-1) - 7

    a. p = 10 + (3) - 7

    a. p = 10 - 21

    = - 11

    a1 = first term

    n = nth term

    d = difference
