An arithmetic sequence has this recursive formula: (a = 5
Tar = 2n-1-4
-
an
What is the explicit formula for this sequence?
O A. an = 5+ (n − 1)(-4)
O B. an= (-1) + (n - 5)(-4)
O C. an = 5+ (n - 4)(-1)
O D. an = (-4) + (n-1)5

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
