Step-by-step explanation:

 Given :

We have to evaluate the sum.

Consider , the given sum

Apply the sum rule,    

we have,

Consider first,

Applying sum formula,

Here, n = 4, we get,

Now consider

Therefore,

Thus,

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases
