Answer: a6=70
Step-by-step explanation:
we know that
In the Arithmetic Sequence the formula is:
an= a1 + d(n−1)
where
a1 is the first term
d is the common difference
n is the number of terms
in this problem
a1=5
a2=18
a3=31
a4=44
a5=57
so
d=a2-a1 or a3-a2 or a4-a3 or a5-a4
d=57-44----> 13
find a6
a6= a1 + d(n−1)
n=6
d=13
a1=5
a6=5+13*(6-1)----> a6=5+13*5----> a6=70
Two lines are parallel if they have the same slope. Computing for the slope of line segment ab and line segment cd using m=(y2-y1)/x2-x1):
m of ab=(2-1)/(2-1)=1 m of cd=<span>(4-3)/(4-3)=1
Since line segment ab and line segment cd have the same slope which is 1, then they are said to be parallel. </span>
The answer is 22 46/49
Answer:
= 2248/1 ÷ 98/1
= (2248 × 1) / (98 × 1)
= 2248/98
= 1124/49

Mean - add up all of the scores, and divide it by the number of members:
68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
462 / 7 = 66
ANSWER: The mean is 66
Median - write out all the numbers in order, and select the middle value:
60, 62, 64, 66, 68, 70, 72
ANSWER: As you can see, 66 is the middle value.
Midrange - find the mean (average) of the smallest and largest number:
Largest number: 72
Smallest number: 60
Midrange: 72 + 60 = 132
132 / 2 = 66
ANSWER: So the midrange is 66
X=3 (the line is on the x-axis, positive because it’s on the positive quadrant)
