5) Read a number entered by the user and display on the screen your next 7 numbers, on the same line, separated by comma and space.

 6) Read a number entered by the user and display all the previous numbers up to zero, line by line.

7) Create a program that prompts the user for the first number. Show on the screen which number was chosen and if the number is greater than 10 then show your predecessors until you reach number 10.

8) Create a program that reads a number entered by the user and shows on the screen their sum. Continue asking and adding the new number to the previous result, and showing each result after the sum on the screen. The accumulation should only stop if the user reports a negative number.

9) Create a program that prompts the user for two start and end numbers and shows on the screen a countdown that starts at the number entered for the beginning and goes to the number entered as end.

10) Create a program that reads a number entered by the user and shows on the screen its subtraction. Continue asking and subtracting the new number from the previous result, and showing each result after subtraction on the screen. The decrease should only stop when the value is zero or less.
