20 days
x=number of days vacation
y=daily expenses
xy=1100
(x+2)(y-5)=1100
*******
xy-5x+2y-10=1100
xy-5x+2y=1110
y=1100/x
x(1100/x)-5x+2(1100/x)=1110
1100-5x+(2200/x)=1110
-5x+(2200/x)=10
-5x^2 + 2200 = 10x
-x^2 + (440) = 2x
x^2 - 440 + 2x = 0
(x+22)(x-20)=0
x=-22,20
only take the positive answer because the negative answer doesn't make sense in the question
so the answer is 20

I might be wrong; this question probation should've been this hard so I might have taken a wrong turn somewhere. feel free to double check my work

The first term is 0. The fourth is 1000. The eighth term is 10,000,000. All you have to do is plug the term you want to find into n and then solve.
Answer:
2x² + 3x + 4
Step-by-step explanation:
Using synthetic division to divide by x - 1
1 | 2 1 1 - 4
↓ 2 3 4
---------------------
2 3 4 0 ← remainder = 0
-----------
↑ quotient
quotient = 2x² + 3x + 4
