Calculate S$20$ using a for loop. Save your answer in the variable A$5.$

$(2)$ Calculate S$200$ using a for loop. Save your answer in the variable A$6.$

$(3)$ Calculate the smallest number n such that Sn $>10.$ Save the corresponding value of n in a variable

named A$7$ and the corresponding value of Sn in a variable named A$8.$

$(4)$ Calculate the smallest number n such that Sn $>20.$ Save the corresponding value of n in a variable

named A$9$ and the corresponding value of Sn in a variable named A$10.$ Warning: If you are not

careful, this code will be extremely slow. You should be able to write a solution that

finishes in at most a few seconds, but it is also possible to write a solution that takes

several minutes. Gradescope has a time limit$,$ and so you will only get credit if your

solution finishes in a reasonable amount of time.
