Answer: The correct option is B. The third term is 4.
Explanation:
The given recursive formula is,
![a_n=\frac{2+a_{n-1}}{2}](https://tex.z-dn.net/?f=a_n%3D%5Cfrac%7B2%2Ba_%7Bn-1%7D%7D%7B2%7D)
It is given that the first term is 10. So,
![a_1=10](https://tex.z-dn.net/?f=a_1%3D10)
To find third term, first we have to find the second term.
![a_2=\frac{2+a_{2-1}}{2}](https://tex.z-dn.net/?f=a_2%3D%5Cfrac%7B2%2Ba_%7B2-1%7D%7D%7B2%7D)
![a_2=\frac{2+a_{1}}{2}](https://tex.z-dn.net/?f=a_2%3D%5Cfrac%7B2%2Ba_%7B1%7D%7D%7B2%7D)
![a_2=\frac{2+10}{2}](https://tex.z-dn.net/?f=a_2%3D%5Cfrac%7B2%2B10%7D%7B2%7D)
![a_2=\frac{12}{2}](https://tex.z-dn.net/?f=a_2%3D%5Cfrac%7B12%7D%7B2%7D)
![a_2=6](https://tex.z-dn.net/?f=a_2%3D6)
Therefore the second term is 6.
![a_3=\frac{2+a_{3-1}}{2}](https://tex.z-dn.net/?f=a_3%3D%5Cfrac%7B2%2Ba_%7B3-1%7D%7D%7B2%7D)
![a_3=\frac{2+a_{2}}{2}](https://tex.z-dn.net/?f=a_3%3D%5Cfrac%7B2%2Ba_%7B2%7D%7D%7B2%7D)
![a_3=\frac{2+6}{2}](https://tex.z-dn.net/?f=a_3%3D%5Cfrac%7B2%2B6%7D%7B2%7D)
![a_3=\frac{8}{2}](https://tex.z-dn.net/?f=a_3%3D%5Cfrac%7B8%7D%7B2%7D)
![a_3=4](https://tex.z-dn.net/?f=a_3%3D4)
Therefore, the correct option is B. The third term is 4.
