Linear Equations using Arithmetic and Geometric Sequences An Arithmetic Sequence of six numbers begins with 7 and ends with 27. A) Name two points on the graph of this sequence (_,7),(_,27) My Answer: (1,7,) (6,27) B) Plot the two points you named in 11 a and find the slope of the line connecting the points My Answer: Using y2-y1/x2-x1 I found the slope (m) as m=4 C) Use the slope to find the missing terms My answer: y=4x+3 (B=3 because when I find the difference between 27 and 7 - 20 - and then divide by the difference between the 6 and 1 - 5 - you get four and then subtract four from seven once to get the 0th term of the arithmetic sequence) and the points would then equal 3, u0=3, u1= 7 u2= 11 u3=15 u4=19 u5= 23 u6=27 D) Plot all the points and write the equation of the line that contains them. My Answer: N/A, I don't understand what this question is asking October 5th, 2016, 02:49 PM   #2
