Complete this finite series.

5, 1 , 2, 5 , 7,...

Spoilerise the important parts of your answers.

No takers? I will reveal the next element in the series.

Uncwilly · 2004-08-21, 23:19

Next element is : 3

again this is a finite series. This is a lateral thinking problem, so you can never solve it with math (although math can help).

There are 12 elements in this series.

Obviously nobody is interested......

So here is the answer:
Numeric representation of the day of the week for the first day of the month for this year.

I use a shifted version of that sequence to quickly calculate the day of the wee for any day.
1, 4, 4, 0, 2, 5, 0, 3, 6, 1, 4, 6
is easy to remember
144, 025, 036, 146

Add the number of the day in the month and also 2 for 2003, 4 for 2004, 5 for 2005, 6 for 2006, 0 for 2007

calculate the result mod 7, then convert

0 for saturday, 1 for sunday, 2 for monday...
