Here are the instructions:
-Write a program that asks for a range of integers and then prints the sum of the numbers in that range (inclusive).
- I defined a formula which asks for the range of integers and then prints the sum of the numbers in that range. I first asked for the list of number between the lower and upper bound thanks to the formula range(). Notice that I wrote y+1 as Python3 does not include the upper bound. Secondly, I just needed to use the formula sum() for the range.
- Print everything and there you go!
-Just for fun, what is the mathematical formula to do this calculation?
Let n+1 be the number of integers between the two boundaries. The mathematical formula is
Sum=N+1(First + Last)/2
