The sequence N: 1, 2, 3, 4, 5; F(n): 12, -36, 108, -324, 972 is,
C) geometric sequence; common ratio is - 3.
An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
By observing the sequence N: 1, 2, 3, 4, 5; F(n): 12, -36, 108, -324, 972,
we can surely conclude that this is not an arithmetic sequence because the difference between the terms is not the same.
We know, In a geometric sequence numbers are written in the same constantratio(r), Therefore,
972/- 324 = - 324/108 = 108/ - 36 = - 36/12 = - 3.
So, It is a geometric sequence with a common ratio of - 3.

Show your work and show each step.
also the direction is anti clockwise
I hope it could help you :)
To draw a 30° angle in standard position on the coordinate plane, start by drawing the initial side of the angle which is the positive x-axis. Use a protractor to measure a 30° angle counterclockwise from the initial side. Then draw a line from the origin to the endpoint of the angle to represent the terminal side. Label the angle measure as 30° and label the terminal side accordingly. Indicate the direction of rotation by drawing an arrow showing the counterclockwise direction.
To draw a 30° angle in standard position on the coordinate plane, follow these steps:

Answer:
8 guest rode in each suburban .
Step-by-step explanation:
As given
victoria invited 260 people to her quinceanera party.
76 guest rode in corvettes and the rest rode in 23 suburbans.
As 76 guest rode in corvettes .
Thus
Number of guest rode in suburbans = 260 - 76
= 184 peoples
Let us assume that the number of guest rode in each suburban be x.
Total suburbans are 23.
Than the equation becomes
x × 23 = 184
x = 8
Therefore 8 guest rode in each suburban .
