  2. If you sequence are :

    - 0.8 , - 3.2 , - 12.8 , - 51.2

    then:

    a1 = - 0.8 = - 0.2 * 4 = - 0.2 * 4 ^ 1

    a2 = - 3.2 = - 0.2 * 16 = - 0.2 * 4 ^ 2

    a3 = - 12.8 = - 0.2 * 64 = - 0.2 * 4 ^ 3

    a4 = - 51.2 = - 0.2 * 256 = - 0.2 * 4 ^ 4

    So:

    an = - 0.2 * 4 ^ n

    a5 = - 0.2 * 4 ^ 5 = - 0.2 * 1024 = - 204.8
