Answer:
the actual answer is a(n)= 500 * ( 1 + 0.03) ^(n - 1) ;$579.64
Step-by-step explanation:
<u>Answer:</u>
The correct answer option is: 19, 13, 3, -11, -29.
<u>Step-by-step explanation:</u>
We are given the following explicit formula for an arithmetic sequence:
![a_n=21-2n^2](https://tex.z-dn.net/?f=a_n%3D21-2n%5E2)
So to find the first five terms of this sequence, we will substitute the values of
(num here in the given formula:
![a_1=21-2(1)^2\\\\a_1=19](https://tex.z-dn.net/?f=a_1%3D21-2%281%29%5E2%5C%5C%5C%5Ca_1%3D19)
![a_2=21-2(2)^2\\\\a_2=13](https://tex.z-dn.net/?f=a_2%3D21-2%282%29%5E2%5C%5C%5C%5Ca_2%3D13)
![a_3=21-2(3)^2\\\\a_3=3](https://tex.z-dn.net/?f=a_3%3D21-2%283%29%5E2%5C%5C%5C%5Ca_3%3D3)
![a_4=21-2(4)^2\\\\a_4=-11](https://tex.z-dn.net/?f=a_4%3D21-2%284%29%5E2%5C%5C%5C%5Ca_4%3D-11)
![a_5=21-2(5)^2\\\\a_5=-29](https://tex.z-dn.net/?f=a_5%3D21-2%285%29%5E2%5C%5C%5C%5Ca_5%3D-29)
Therefore, the first five terms of the sequence defined by the explicit formula
are 19, 13, 3, -11, -29.
Answer:
z = 110
Step-by-step explanation:
z + 35 + 35 = 180
z+70=180
z = 110
