  1. Answer:

    Fourth term of given arithmetic progression a(4) = 30

    Step-by-step explanation:

    Given incomplete information:

    a(n) = 7n – 1 9

    Assume Correct information:

    a(n) = 7(n – 1) + 9

    Find:

    Fourth term of given arithmetic progression

    Computation:

    Fourth term of given arithmetic progression = a(4)

    So,

    Number of term (n) = 4

    So,

    a(n) = 7(n – 1) + 9

    a(4) = 7(4 – 1) + 9

    a(4) = 7(3) + 9

    a(4) = 21 + 9

    a(4) = 30

    Fourth term of given arithmetic progression a(4) = 30
