    Step-by-step explanation:

    b (1) = - 7

    The 4th term is b (4).

    b (n) = b (n - 1) + 12

    b (2) = b (1) + 12 = - 7 + 12 = 5

    b (3) = b (2) + 12 = 5 + 12 = 17

    b (4) = b (3) + 12 = 17 + 12 = 29

    b (4) = 29

    Step-by-step explanation:

    b (1) = - 7

    b (n) = b (n - 1) + 12

    b (2) = b (2-1) + 12 = b (1) + 12 = - 7+12 = 5

    b (3) = b (3-1) + 12 = b (2) + 12 = 5+12 = 17

    b (4) = b (4-1) + 12 = 17+12 = 29
