Answer:
A)29 and B) 21,
Step-by-step explanation:
First,in the sequence
, the parameter
must to be a integer.
Second, we need to solve the equations by
.
![n=(a_n+7)/4](https://tex.z-dn.net/?f=n%3D%28a_n%2B7%29%2F4)
All the option in the problem represent an
Then, we need to prove all number in the options, if the result is a integer number, this option can be part of the sequence.
For A)
![n=(29+7)/4=9\\](https://tex.z-dn.net/?f=n%3D%2829%2B7%29%2F4%3D9%5C%5C)
For B)
![n=(21+7)/4=7\\](https://tex.z-dn.net/?f=n%3D%2821%2B7%29%2F4%3D7%5C%5C)
For C)
![n=(20+7)/4=6.75\\](https://tex.z-dn.net/?f=n%3D%2820%2B7%29%2F4%3D6.75%5C%5C)
For D)
![n=(28+7)/4=8.75\\](https://tex.z-dn.net/?f=n%3D%2828%2B7%29%2F4%3D8.75%5C%5C)
Only A) and B) only A and B meet the requirement

Answer:
The Answer is: 78.
Step-by-step explanation:
This one makes you think!
Let n = the number.
The number is greater than 50 and less than 85:
50 < n < 85
Some of the factors are 13 and 3.
So, multiply 13 * 3 = 39.
Multiply again by 2:
39 * 2 = 78.
78 can be factored as:
13 * 3 * 2 = 78, and it is greater than 50 and less than 85.
The number is 78.
Hope this helps! Have an Awesome Day!! :-)
