What kind of sequence is the pattern 1 6 7 13 20?

Answer 1

Oh, dude, that's an arithmetic sequence. You know, like when you add the same number each time to get to the next number. In this case, you're adding 5, then 6, then 7... you get the idea. It's like a math puzzle, but with less excitement.

Answer 2

There are many possible answers. But given 5 points, an answer that can be guaranteed is that it is a polynomial of degree 4 (a quartic).

In this case, Un = (-13n4 + 166n3 - 719n2 + 1310n - 720)/24
