Who Ordered the Pi? (Posted on 2003-04-21) Difficulty: 4 of 5
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.

Solution re: Word problem??? - maths bit | Comment 4 of 11 |
(In reply to Word problem??? by fwaff)

Sorry, I should have put this on the end of my previous post...

A mathematical function that gives the sequence is:

(floor(n/6))pi + (1-floor(n/6))n^2

for n=1 to 5 this is equivalent to 0pi + 1n^2 = n^2
for n=6 this is 1pi + (1-1)6^2 = pi
for n=7 to 11 this is 1pi + (1-1)n^2 = pi
for n=12 this is 2pi - 144

Again I guess that this is A solution rather than THE solution.
