Step-by-step explanation:
⇒12)It is an arithmetic sequence.
d=2-1=3-2=4-3=1
a(n) = a +(n-1)d
a(n) = 1+(n-1)1
The next three terms:
a(6) = 1+(6-1)1=6
a(7) = 1+(7-1)1=7
a(8) = 1+(8-1)1=8
⇒13)It is an arithmetic sequence.
d=0-3=-3-0=-6+3=-3
a(n) = a +(n-1)d
a(n) = 3+(n-1)-3
The next three terms:
a(5) = 3+(5-1)-3=-9
a(6) = 3+(6-1)-3=-12
a(7) = 3+(7-1)-3=-15
⇒14)It is <u>not </u>an arithmetic sequence.
⇒15) a(50) = 10 +(50-1)5
=<u>255</u>

Answer:
Y=X-7
Step-by-step explanation:
I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
Answer:
26.5454545455
Step-by-step explanation:
1. To answer this question we must keep on mind that we already have the distance from Cleveland to Cincinnati.
2. They tell us that it is 40 centimeters on the first map.
3. If on the first map then:
4. Then the distance from Cleveland to Cincinnati is 400 kilometers.
5. On the second map
6. Then we want to know how many centimeters represents 400 kilometers on the second map. Therefore:
The answer is: 8 centimeters.
