Since is arithmetic, it's given recursively by
where is a fixed number and is the starting term in the sequence. We have
and so on, so that
We're told that , so
and
so that
Then the first term in the sequence is :
and the sequence has general formula
The first negative term occurs for
The first negative term in the sequence is .

Answer: D Equilateral
Step-by-step explanation: Center of a triangle is a point where lines intersect. There 4 most popular: centroid, circumcenter, orthocenter and incenter.
<u>Altitude</u> or <em><u>Height</u></em> of a triangle is a perpendicular line is draw from a vertex to the opposite side. There are 3 heights and they united (or intersect) at a point called <em>Orthocenter</em>
<u>Incenter</u> is a point where the three <u>angle</u> <u>bisectors</u> meet. Angle bisector is a line that divide the angles of the triangle in two equal angles.
Generally, each center is positioned at a different location on the triangle (in one example, the point is located outside the triangle).
<u>However, there is a case in which incenter and orthocenter are coincidental. That case is for a equilateral triangle</u>, a triangle whose angles and sides are the same.
Answer:
Step-by-step explanation:
Multiply 255.38 times 0.20 (20%). You get 51.076. Subtract 51.076 from 255.38. You get 204.304. Multiply this by 0.11 (11%). You get 22.47344. Add this to 204.304. You end with 226.77744. Divide this by 4. You get 56.69436 or $56.69 a piece.
