Answer:
64. 6138
66. 8.078125
Step-by-step explanation:
Let's take it one number at a time.
For number 64:










Sum = 6 + 12 + 24 + 48 + 96 + 192 + 384 + 768 + 1536 + 3072
Sum = 6138
For number 66:










Sum = 12 + -6 + 3 + -1.5 + 0.75 + -0.375 + 0.1875 + -0.0078125 + 0.046875 + -0.0234375
or to make things simpler:
Sum = 12 - 6 + 3 - 1.5 + 0.75 - 0.375 + 0.1875 - 0.0078125 + 0.046875 - 0.0234375
Sum = 8.078125
