Answer:
-5n + 20
Step-by-step explanation:
n stands for the term number so if you want to find the 50th term all you have to do is substitute n with 50
first of all find the difference between each number in the sequence
the difference between 25 and 20 is -5
the difference between 20 and 15 is -5
the difference between 15 and 10 is -5
the difference between 10 and 5 is minis -5
because
25-5=20
20-5=15
15-5=10
10-5=5
now that you know the the difference you place the number in front of n like this
-5n
to find the rest all you need to do is use the difference between each number which is -5 and do it on the first number
so 25 - 5
this gives 20
so our nth term is -5n + 20
if you still don't get i can re-explain it to you

Answer:
The midpoint is (4,3)
Step-by-step explanation:
I attached the midpoint formula.
<u>( -1 + 9 )</u> <u>( 4 + 2 )</u>
2 2
8 / 2 = 4 6 / 2 = 3
(4,3)
Center; (-1, 3)
foci; (2, 3), (-4, 3)
vertices; (4, 3), (-6,3)
