Answer: x ≥ 4
<u>Step-by-step explanation:</u>
x + 10 ≥ 14
Subtract 10 from both sides of the equation:
x ≥ 4
Graphing:
> and < symbols represent an open dot
≥ and ≤ symbols represent a closed dot
Since the solution is: x ≥ 4, we will use a closed dot and the arrow will point to the right of 4.

Given that the recursive formula for a sequence is ![a_n=a_{n-1}+2n](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D%2B2n)
The first term of the sequence is ![a_1=4](https://tex.z-dn.net/?f=a_1%3D4)
We need to determine the first four terms of the sequence.
<u>Second term:</u>
The second term of the sequence can be determined by substituting n = 2 in the recursive formula.
Thus, we have;
![a_2=a_{2-1}+2(2)](https://tex.z-dn.net/?f=a_2%3Da_%7B2-1%7D%2B2%282%29)
![a_2=a_{1}+2(2)](https://tex.z-dn.net/?f=a_2%3Da_%7B1%7D%2B2%282%29)
![a_2=4+4](https://tex.z-dn.net/?f=a_2%3D4%2B4)
![a_2=8](https://tex.z-dn.net/?f=a_2%3D8)
Thus, the second term of the sequence is 8.
<u>Third term:</u>
The third term of the sequence can be determined by substituting n = 3 in the recursive formula.
Thus, we have;
![a_3=a_{3-1}+2(3)](https://tex.z-dn.net/?f=a_3%3Da_%7B3-1%7D%2B2%283%29)
![a_3=a_{2}+2(3)](https://tex.z-dn.net/?f=a_3%3Da_%7B2%7D%2B2%283%29)
![a_3=8+6](https://tex.z-dn.net/?f=a_3%3D8%2B6)
![a_3=14](https://tex.z-dn.net/?f=a_3%3D14)
Thus, the third term of the sequence is 14.
<u>Fourth term:</u>
The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.
Thus, we have;
![a_4=a_{4-1}+2(4)](https://tex.z-dn.net/?f=a_4%3Da_%7B4-1%7D%2B2%284%29)
![a_4=a_{3}+2(4)](https://tex.z-dn.net/?f=a_4%3Da_%7B3%7D%2B2%284%29)
![a_4=14+8](https://tex.z-dn.net/?f=a_4%3D14%2B8)
![a_4=22](https://tex.z-dn.net/?f=a_4%3D22)
Thus, the fourth term of the sequence is 22.
Hence, the first four terms of the sequence is 4, 8, 14, 22.
