Answer 6

notice, how did they get from 64 to 16, and how did they then get from 16 to 4, well\[\frac{ 64 }{ 4 }=16\]\[\frac{ 16 }{ 4 }=4\]so that means every number is being divided by 4, you could also notice that\[\frac{64}{4^0} \rightarrow\frac{ 64 }{ 4^1 } \rightarrow \frac{ 64 }{ 4^2 } \rightarrow \frac{ 64 }{ 4^3 }\] is the sequence that you have,

Answer 7

by following this pattern, you'll get that the 10th number in the sequence is\[\frac{ 64 }{ 4^9 }=\frac{ 1 }{ 4096 }\]
