Answer:
![2^5](https://tex.z-dn.net/?f=2%5E5)
Step-by-step explanation:
Given:
![(13^4 - 11^4)(13^2+11^2)](https://tex.z-dn.net/?f=%2813%5E4%20-%2011%5E4%29%2813%5E2%2B11%5E2%29)
add all together with exponents
=48*290
= Then turn into a smaller exponent
= ![2^4 * 3 * 2*145](https://tex.z-dn.net/?f=2%5E4%20%2A%203%20%2A%202%2A145)
combine like terms
![2^4 *2](https://tex.z-dn.net/?f=2%5E4%20%2A2)
=![2^5](https://tex.z-dn.net/?f=2%5E5)

we know that
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
![a_n=r^{n-1}](https://tex.z-dn.net/?f=a_n%3Dr%5E%7Bn-1%7D)
where
a_n---->
term of the sequence
r ---> is the common ratio
a ---> the first term of the sequence
![a=50\\r=100\%-10\%=90\%=90/100=0.90](https://tex.z-dn.net/?f=a%3D50%5C%5Cr%3D100%5C%25-10%5C%25%3D90%5C%25%3D90%2F100%3D0.90)
substitute
![a_n=50(0.90)^{n-1}](https://tex.z-dn.net/?f=a_n%3D50%280.90%29%5E%7Bn-1%7D)
For n=12
substitute
![a_n=50(0.90)^{12-1}=16](https://tex.z-dn.net/?f=a_n%3D50%280.90%29%5E%7B12-1%7D%3D16)
