... sequence are called terms. If you can always add the same number to the previous term to find the next term, the sequence is an arithmetic sequence. If you can always multiply the previous term by the same number to find the next term, the sequence is a geometric sequence. • To test for an arithmeti ...

Pascal
... 52 rows of Pascal’s triangle, and then start at the left end of the 52nd row and count to 13 (starting at 0). But that just might be a lot of work (truly!). Is there a better way? The answer is yes––yes there is. There is a wonderful argument which produces a simple formula. For example, suppose you ...

A New Connection Between the Triangles of Stirling and Pascal
... number! That’s true, Pascal’s triangle doesn’t always yield perfect numbers in this manner, but every even perfect number does appear somewhere in this sequence. This is because the number of elements in each white triangle is given by 2n –1(2n – 1). With n = 1, we get 1. Making n = 2 or 3 gives 6 a ...
