Answer:
For an nth term U(n) = a + (n -1)d
n = number of terms
a = first term
d = common difference
a = 8
d = 16 - 8 = 8
U(n) = 8 + (n-1)8
= 8 + 8n - 8
= 8n
The formula for the sequence is 8n

First, let's declare that the average of the two integers would be 22.5. Using this, we are going to try and find two consecutive integers that have an average of 22.5. We can start to work outward from this average and see what integers work.
Instantly, we can test the integers 22 and 23. They have an average of 22.5 and sum to 45. Thus, they are our answer.
You have to distribute the 3.
3*4x , 3*-5
12x - 15

Answer:
19/36 more than yesterday
Step-by-step explanation:
Since the denominators are different, multiply each fraction by the denominator of the other to be the same.
1/4 * 9 = 9/36
7/9 * 4 = 28/36
Now that the denominators are the same, you can subtract:
28/36 - 9/36 = 19/36
Answer:
-12-9--7= -14
Step-by-step explanation:
1 -12-9--7=
2 -21--7= (minus negative equals plus)
3 -21+7=14
