i) Write a Sigma-notation summation for: the sum of the first “n” odd positive integers. For example, if n=4, it should sum like this: 1 + 3 + 5 + 7. ii) Starting with: 1+sum r^n, n=1 to infinity, rewrite it as just one summation without the 1+ out front. iii) Starting with: sum 1/n, n=1 to infinity, rewrite it as two terms out front, and then the sum starting at n=3. iv) Starting with: sum 1/(n+1), n=0 to 5,...

4.47 Create a Visual Basic project to determine the sum of the first n positive integers (that is, determine the sum 1 + 2 + 3 + . . . + n). Specify n as an input parameter, via an appropriately labeled text box. Use a loop structure to calculate the sum. Display the sum in a separate text box, with an appropriate label.

27.5 Loops (nested)**: Sum a given number of integers A user will enter an initial number, followed by that number of integers. Output those integers' sum. Repeat until the initial number is O or negative. Ex: If the user enters 3 96 1 0, the output is 16 Ex: If the user enters 396125 3 0, the output is 16 Hints: Use a while loop as an outer loop.

Challenge activity: A partition of a positive integer n is the expression of n as the sum of positive integers, where order does not matter. For example, two partitions of 7 are 7 1+1+1+4 and 7=1+1+1+2+2. A partition of n is perfect if every integer from 1 to n can be written uniquely as the sum of elements in the partition. 1+1+1+4 is perfect since 1-7 are expressed only as 1, 1+1, 1+1+1, 4, 1+4, 1+1+4 and 1+1+1+4, but 1+1+1+2+2...
