What is the 100th pentagonal number?

How do you find the 100th term of a sequence in nth?
you replace the "n" with ahundred e.g... if it's 2n+1, you will go 2x100+ 1 which is 201
How do you find the 100th triangle number?
The nth triangulat number is n*(n+1)/2 The 100th is 100*101/2 = 5050
How is the recursive form of a sequence sometimes more useful than the closed form where a rule is found to find any term based on its position in the sequence?
"The recursive form is very useful when there aren't too many terms in the sequence. For instance, it would be fairly easy to find the 5th term of a sequence recursively, but the closed form might be better for the 100th term. On the other hand, finding the closed form can be very difficult, depending on the sequence. With computers or graphing calculators, the 100th term can be found quickly recursively."
