answer
42-12=30 check
The next term is double the previous term, so that the
-th term is given recursively by
![\begin{cases}a_1=1\\a_n=2a_{n-1}&\text{for }n>1\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7Da_1%3D1%5C%5Ca_n%3D2a_%7Bn-1%7D%26%5Ctext%7Bfor%20%7Dn%3E1%5Cend%7Bcases%7D)
This rule tells us that
![a_2=2a_1](https://tex.z-dn.net/?f=a_2%3D2a_1)
![a_3=2a_2=2^2a_1](https://tex.z-dn.net/?f=a_3%3D2a_2%3D2%5E2a_1)
![a_4=2a_3=2^3a_1](https://tex.z-dn.net/?f=a_4%3D2a_3%3D2%5E3a_1)
and so on, with the explicit rule
![a_n=2^{n-1}a_1=2^{n-1}](https://tex.z-dn.net/?f=a_n%3D2%5E%7Bn-1%7Da_1%3D2%5E%7Bn-1%7D)
for
.
If 512 is the
-th term in the sequence, then
![512=2^{k-1}\implies\log_2512=\log_22^9=\log_22^{k-1}\implies9=k-1\implies k=10](https://tex.z-dn.net/?f=512%3D2%5E%7Bk-1%7D%5Cimplies%5Clog_2512%3D%5Clog_22%5E9%3D%5Clog_22%5E%7Bk-1%7D%5Cimplies9%3Dk-1%5Cimplies%20k%3D10)
