Answer:
An arithmetic sequence is a sequence with the difference or pattern between two consecutive terms constant.
A geometric sequence is a sequence with a ratio between two consecutive terms constant.
<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by
![(x, y) \Rightarrow(-y, x)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%5CRightarrow%28-y%2C%20x%29)
Substituting the coordinates of the point C in the above formula, we get;
![(2, 1) \Rightarrow(-1, 2)](https://tex.z-dn.net/?f=%282%2C%201%29%20%5CRightarrow%28-1%2C%202%29)
Therefore, the coordinates of the point C' is (-1,2)
Yes because 26 is an even number
