Each year, the average temperature of a region is increasing by 2.5degrees Celsius. If the average temperature recorded in 2014 was 27degrees Celsius, what will be the average temperature in the 10th year?

### Re: Sequences problem (Help please).

Hi Ganesh, i also arrived to the same conclusion as you but my book say's the answer is 28 degrees Celsius, is there a flaw in mine and your calculations?

Hi coolboyx12,

I am unable to decipher the book answer at 28 degrees Celsius.

I'm getting 49.5

28 must be an error.

But, .... not a very realistic question ... 2.5 every year is serious global warming!

Well, i guess i just have to stick to 49.5, thanks for answering, and yeah bob it's serious global warming, this is a significant increase in temperature, but it is not enough to cause immediate death for most people. However, such a significant increase in temperature would have severe consequences for the environment and the planet, including more frequent and intense heat waves, droughts, wildfires, and other extreme weather events. It could also have negative impacts on agriculture, biodiversity, and human health, among other things. Therefore, it is important to take action to address climate change and reduce greenhouse gas emissions to prevent such a scenario from happening.
