Question 1199534
<br>
One and only one problem per post!<br>
These two problems are on completely different subjects, so they clearly should be submitted separately.<br>
A comment on the first problem only....<br>
Calculating the 34th and 44th numbers in the Fibonacci sequence is an exercise that teaches absolutely nothing useful.  Look up the answer on the internet.  Or you can learn something about spreadsheets by finding the answer using a spreadsheet.<br>
