Answer:
an = -9 + 7( n - 1)
Step-by-step explanation:
an = first term + difference (n-1)
First term = 9
Difference = -2 - -9 = -2 + 9 = 7
an = -9 + 7( n - 1)
You can check this by substituting the values in.
a1 = -9 + 7(0) = -9
a2 = -9 + 7(2) = -9 + 7 = -2
a3 = -9 + 7(3) = -9 + 14 = 5
Answer:
Coordinates of midpoint are (8,1.5).
Step-by-step explanation:
Given coordinates of end points are;
(7,4) and (9,-1)
we can find the coordinates of mid-point,
Here,
x1 = 7 and y1 = 4
x2 = 9 and y2 = -1
Putting these values in formula
Coordinates of mid point =
Midpoint =
Midpoint =
Midpoint = 8 , 1.5
Hence,
Coordinates of midpoint are (8,1.5).
