是一道英语的数学题 请求哥哥姐姐们帮助!感激不尽!
The points on this graph represent the first five terms of an arithmetic
sequence.The height of each point is its distance from the x-axis,or
the value of the y-coordinate of the point.
a.Find u0,the y-coordinate of the point preceding those given.
b.How many common differences (d's) do you need to get from the
height of (0,u0) to the height of (5,u5)?
c.How many d's do you need to get from the height of (0,u0) to
the height of (50,u50)?
d.Explain why you can find the height from the x-axis to (50,u50) using the equation u50 = u0 + 50d.
e.In general,for an arithmetic sequence,the explicit formula is un = .

Answer 1

这个图上的点代表了一个算术方面第一个五年序列.每个点的高度是其从X轴,或距离在Y坐标点值. 答：查找用U0的Y坐标上的特定点. 湾多少（D的）共同的差异,你需要获得从高度（0,用U0）到高（5,U5区）? 角...
