Answer:
![a_1 = -11\\\\a_n = a_{(n - 1)} + 22](https://tex.z-dn.net/?f=a_1%20%3D%20-11%5C%5C%5C%5Ca_n%20%3D%20a_%7B%28n%20-%201%29%7D%20%2B%2022)
Step-by-step explanation:
An arithmetic sequence is generally given as:
f(n) = a + (n - 1)d
where a = first term and f(n) = nth term, d = common difference
The explicit formula given is:
f(n) = 11 + 22(n - 1)
The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.
Mathematically, it is given as:
![a_1 = a\\\\a_n = a_{(n - 1)} + d](https://tex.z-dn.net/?f=a_1%20%3D%20a%5C%5C%5C%5Ca_n%20%3D%20a_%7B%28n%20-%201%29%7D%20%2B%20d)
Therefore, the recursive formula is:
![a_1 = -11\\\\a_n = a_{(n - 1)} + 22](https://tex.z-dn.net/?f=a_1%20%3D%20-11%5C%5C%5C%5Ca_n%20%3D%20a_%7B%28n%20-%201%29%7D%20%2B%2022)

Replace x with 0.5
3+4(0.5)-2(0.5)
Now multiply
3+2-1
5-1
Answer: 4
(x + 6)(4x + 1)
x times 4x = 4x^2
x times 1 = x
6 times 4x = 24x
6 times 1 = 6
<span>And finally, by adding like terms, 4x^2 + 25x + 6
I hope this helps you! Good luck :)</span>
