 Who Ordered the Pi? (Posted on 2003-04-21)
What is the next number in this sequence?

1, 4, 9, 16, 25, pi

The sequence is not arbitrary. Create a mathematical function that generates this sequence.

 Submitted by Bryan Rating: 1.7778 (9 votes) Solution: (Hide) Like most questions (in life, as in Flooble-space), there is more than one possible answer. One solution is to define the nth term of this sequence as n^2 + (pi-36)(n-1)(n-2)(n-3)(n-4)(n-5)/5! For n=1 to 5, the second term equals zero. For n=6, the expression simplifies to 36 + (pi-36)*5!/5! = pi. The next term in this sequence (n=7) is36 + (pi-36)6!/5! = 6*pi - 180
