How Long?
Math brain teasers require computations to solve.
What is the number pattern?
31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334, 365

Answer
The pattern is every month, starting from January going to December. The numbers are the number of days in each month, and each time the pattern goes on, that number is added to the total. Here are the month's days in order from January to December:
31

| Good Work Met: I was off. too eager. I thought in Degrees until I saw the 365, but I still didn't get it. Very Nice, difficult, but somewhat simple while Tickling the Brain. Good work.  |

| Nice teaser, pretty easy. Once I started finding the differences between each value the pattern became clear.
However, this seems like it belongs in the "series" category as there is no math involved. |
