Monday -4 degrees Fahrenheit increase 6 degrees. On Tuesday it increased 2 degrees. For the next 7 days it increased. What is the temperature on the 9th day?
-4 + 6 + 2(7) =
I put 2+14 = 16
-4 + 6 + 2(7) =
I put 2+14 = 16
To find the temperature on the 9th day, we need to add up all the temperature increases from Monday to the 9th day.
On Monday, there was a 4 degrees Fahrenheit increase. Therefore, the temperature on Monday was 4 degrees + (-4 degrees) = 0 degrees Fahrenheit.
On Tuesday, there was a 2 degrees Fahrenheit increase. Therefore, the temperature on Tuesday was 0 degrees + 2 degrees = 2 degrees Fahrenheit.
Now we need to continue the pattern of temperature increases for the remaining 7 days. Let's calculate the temperature increases for the next 7 days:
Day 1: Increase by 3 degrees (Pattern: increase by 1 degree more each day)
Day 2: Increase by 4 degrees
Day 3: Increase by 5 degrees
Day 4: Increase by 6 degrees
Day 5: Increase by 7 degrees
Day 6: Increase by 8 degrees
Day 7: Increase by 9 degrees
Now let's add up all the temperature increases:
Temperature increase from Day 1 to Day 7 = 3 + 4 + 5 + 6 + 7 + 8 + 9 = 42 degrees Fahrenheit
So, the temperature on the 9th day would be the temperature on Tuesday (2 degrees Fahrenheit) + total temperature increase from Day 1 to Day 7 (42 degrees Fahrenheit) = 2 + 42 = 44 degrees Fahrenheit.
Therefore, the temperature on the 9th day would be 44 degrees Fahrenheit.
