    The 4 t h term is f (4) = 143

    Step-by-step explanation:

    Explanation:-

    Given function f (1) = - 4

    Given 'nth' term is f (n) = - 3f (n-1) + 5

    Put n = 2 f (2) = - 3 f (2-1) + 5

    = - 3 f (1) + 5

    = - 3 (-4) + 5

    = 12 + 5

    f (2) = 17

    put n = 3

    f (n) = - 3f (n-1) + 5

    f (3) = - 3 f (3-1) + 5

    = - 3f (2) + 5

    = - 3 (17) + 5

    = - 51+5

    f (3) = - 46

    Put n=4

    f (n) = - 3f (n-1) + 5

    f (4) = - 3f (4-1) + 5

    f (4) = - 3f (3) + 5

    f (4) = - 3 (-46) + 5

    f (4) = 138 + 5

    f (4) = 143

    Final answer:-

    The 4 t h term is f (4) = 143
