C. 75. The median is the middle number in the sequence
The answer is the furthest to the right.
The answer to the given permutation and combination are
To solve the given problems, we have to use permutation and combination
<h3>Permutation and Combination</h3>
This is a topic in mathematics that deals with the probability or number of ways an event can occur.
a)10P5
![_1_0P_5 = 30240](https://tex.z-dn.net/?f=_1_0P_5%20%3D%2030240)
b) 6C2
![_6C_2 = 15](https://tex.z-dn.net/?f=_6C_2%20%3D%2015)
c) This will be a multiplication of permutation of number. This becomes
![_2_6P_2 * _1_0P_2 = 58500](https://tex.z-dn.net/?f=_2_6P_2%20%2A%20_1_0P_2%20%3D%2058500)
This can happen in 58,500 ways.
d) To arrange 9 blocks in a row, she can do it in
![_9C_1 = 9](https://tex.z-dn.net/?f=_9C_1%20%3D%209)
she can do this in 9 ways
e) This can be solved using combination by writing it as
![_1_0C_5 = 252](https://tex.z-dn.net/?f=_1_0C_5%20%3D%20252)
She can do this in 252 ways.
From the above calculations, the answer to the given permutation and combination are

espero que te sirva mi ayuda
![\boxed{a_{n}=5-2(n-1)}](https://tex.z-dn.net/?f=%5Cboxed%7Ba_%7Bn%7D%3D5-2%28n-1%29%7D)
- The domain is any natural number.

Explanation:</h2>
The arithmetic sequence is defined as Follows:
<em>A sequence of numbers whenever the difference of any two successive members of the sequence remains constant.</em>
The explicit equation of any arithmetic sequence can be written as follows:
![a_{n}=a_{1}+d(n-1) \\ \\ \\ a_{1}: First \ term \\ \\ a_{n}:nth \ term \\ \\ d:Common \ ratio \\ \\ n:Number \ of \ term](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7B1%7D%2Bd%28n-1%29%20%5C%5C%20%5C%5C%20%5C%5C%20a_%7B1%7D%3A%20First%20%5C%20term%20%5C%5C%20%5C%5C%20a_%7Bn%7D%3Anth%20%5C%20term%20%5C%5C%20%5C%5C%20d%3ACommon%20%5C%20ratio%20%5C%5C%20%5C%5C%20n%3ANumber%20%5C%20of%20%5C%20term)
So here we know:
- First term is 5
- Second term is 3
![a_{1}=5 \\ \\ a_{2}=5+d(2-1)=3 \\ \\ \\ Isolating \ d: \\ \\ d=3-5 \\ \\ d=-2](https://tex.z-dn.net/?f=a_%7B1%7D%3D5%20%5C%5C%20%5C%5C%20a_%7B2%7D%3D5%2Bd%282-1%29%3D3%20%5C%5C%20%5C%5C%20%5C%5C%20Isolating%20%5C%20d%3A%20%5C%5C%20%5C%5C%20d%3D3-5%20%5C%5C%20%5C%5C%20d%3D-2)
Finally, the explicit formula is:
![\boxed{a_{n}=5-2(n-1)}](https://tex.z-dn.net/?f=%5Cboxed%7Ba_%7Bn%7D%3D5-2%28n-1%29%7D)
Moreover, the domain is any natural number.
