    127.75

    Step-by-step explanation:

    In this geometric series, it is clear that every number is half of the previous number. From that, we can continue on the series as shown below ...

    64+32+16+8+4+2+1+0.5+0.25

    The series above is 9 total terms. We can add those together to get our answer.

    64+32+16+8+4+2+1+0.5+0.25 = 127.75
