    You are adding three to the last term to get to the next one.

    a = - 5

    d = 3

    Explicit Formula

    tn = a + (n - 1) * d

    Example

    t4 = - 5 + (4 - 1) * 3

    t4 = - 5 + 3*3

    t4 = - 5 + 9

    t4 = 4 which is exactly what you show.

    Recursive formula

    f (n) = f (n - 1) + 3

    Example

    n = 5

    f (5) = f (4) + 3

    f (5) = 4 + 3

    f (5) = 7
