An arithmetic sequence is an ordered list of numbers where the next number is found by adding on to the last number (ex: 2,5,8,11... is a sequence where 3 is added on to find the next number).
The equation for an arithmetic sequence is
is the "n-th" number in the sequence (ex: is the first term in the sequence)
d is the number you add (common difference) to find the next number
The first number in the sequence is 47 so
<span>d=-2 because the question gives you that

Answer:
False
Step-by-step explanation:
False.
The point on the opposite side is not necessarily the midpoint of the opposite side. In fact, the the point does not even have to be on the opposite side.
The altitude of a triangle is a segment whose endpoints are a vertex of the triangle and a point on the line containing the opposite side such that the altitude is perpendicular to that line.
Answer:
55 1/2 feet
Step-by-step explanation:
.25 yards = 9 inches
9 inches x 74 bookmarks= 666 inches
12 inches = 1 foot
666 inches/12 inches = 55.5 feet

- Distribute the 2 to the numbers inside of the parentheses
Answer:
a=4
Step-by-step explanation:
We can see that 64= 4*4*4= 4^3, replacing 64 with 4^3 in the equation:
