Median- 63
mode-60
to find the median you arrange the values from the lowest to highest value, then you find the MIDDLE number.. if theres two in the middle add them and divide by two.
the mode is the Q3 - Q1 (70-60)
I am assuming you want to find r. r = -36
Answer:

Step-by-step explanation:
we know that
Using proportion

Round to the nearest whole number

Given that,
= 39
We will find the second term 

Similarly,

Now we use the option checking method,
Suppose we check 4th option
a_{n}= 6n + 33
for n=1
= 6(1) + 33 = 39

It means option D is correct
Answer:
<U= 75°
<V=65°
x=50
Step-by-step explanation:
The interior angles to a triangle always equal 180°.
Set up your equation:
180= 40+x+15+x+25
Subtract 40 from 180 to get 140. Subtract 15 from both sides. Now you have 125. Subtract the 25 from both sides. You now have 100.
Divide the 100 by 2 to find what x is because your equation is now 100=2x
x=50
v= 50+15= 65 so V is 65°
U is 50+25 so U is 75°
