Answer:
The 80th term would be 647
Step-by-step explanation:
In order to find the 80th term, you need to find the rule for the sequence. You'll notice that the numbers are going up by 8. Since there is no 0th term, the first term would be 8 more than the base.
15 - 8 = 7
Therefore the base is 7. As a result, you can model the sequence as:
An = 8n + 7
In which n is the number in the sequence. Now knowing this, we can plug in 80 and get the answer.
An = 8n + 7
An = 8(80) + 7
An = 640 + 7
An = 647
Answer:
The temperature needs to decrease by 7°F to return to the original temperature.
Step-by-step explanation:
The temperature starts at 33 degrees then increases by 10 then 12 then decreases by 15 which will equal 40.
33 + 10 = 43
43 + 12 = 55
55 - 15 = 40
40 - 33 = 7
The temperature needs to decrease by 7 degrees.
12.57
you can double check though
