How?

OpenStudy (studygurl14):

1, 6, 11...

OpenStudy (studygurl14):

+5?

OpenStudy (perl):

correct

OpenStudy (perl):

actually you can use a linear sequence , also known as arithmetic sequence

OpenStudy (perl):

I thought these were hexagonal numbers :)

OpenStudy (misty1212):

i wonder if by "formula" it is a formula for an arithmetic sequence, or a polynomial of degree two? my guess is the first

OpenStudy (studygurl14):

Would it just be n+5?

OpenStudy (perl):

5n - 4

OpenStudy (perl):

n + 5 : 6, 7, 8, ... different sequence

OpenStudy (studygurl14):

Oh, right. Thanks
