Answer:
0,4,24,60,112
Step-by-step explanation:
an = 8n² − 4n
first 5 terms is a0, a1, a2, a3 and a4
for a0, n = 0,
a0 = 8(0)² − 4(0) = 0
for a1, n = 1,
a1 = 8(1)² − 4(1) = 8-4 = 4
for a2, n = 2,
a2 = 8(2)² − 4(2) = 8(4)- 4(2) = 32-8 = 24
for a3, n = 3,
a3 = 8(3)² − 4(3) = 8(9) − 4(3) = 72 - 12 = 60
for a4, n = 4,
a4 = 8(4)² − 4(4) = 8(16) − 4(4) = 128 - 16 = 112
hence the first 5 terms are
0,4,24,60,112
Answer:
a=9 b=18
Step by-step explanation:
First we will find b.
Because there is no 18 in this set and it's an even set of numbers, this would mean that 18 is not present in the set.
The only way for 18 to the be the mean is for b to equal 19. When calculating the average of 17 and 19 your average, or mean, is 18.
a has to be a number ranging from 7-12.
Through trial and error, it can be found that the missing value of a is 9.
Hope this helps!

Answer:
You have to pay for it
Step-by-step explanation:
Either search it up on google, or steam.
The answer is 100
since the number 100 is the number that appears to be the most frequent
A + C
(-5, -7) is 7 units to the left of point H
(-7, 7) is more than 7 units up and left of point H
the x axis is at (infinity, 0), being only 7 points up from point H
