    Answer:

    -10, -33, -125, -493, -1965

    Step-by-step explanation:

    a_1 = -10

    a_n = 4a_(n – 1) + 7

    The first five terms of the sequence are

    a_1 =                                             -10

    a_2 = 4(-10) + 7     =   -40 + 7 =    -33

    a_3 = 4(-33) + 7    =  -132 + 7 =   -125

    a_4 = 4(-125) + 7  = -500 + 7 =   -493

    a_5 = 4(-473) + 7 = -1972 + 7 = –1965
