### Numbers Sequence 10-29-2011

It’s just about Halloween 2011 and it is the perfect time to introduce a new feature – Numbers Sequence. Essentially, it is a number sequence game – the player guesses the next number in the sequence, and gives the sequence general formula.

This game is video based. Just watch the video and note the numbers that come up. The numbers are part of a regular sequence of numbers. This is the first video in this series. If it is well received, I will generate more.

Here is the video – be sure to write the numbers down!

Can you guess the next number and general formula? If you give up, just scroll down for the answers. Beware – SPOILERS!

283985 is the next number in the sequence. The general formula is 13+((n-1)x4), not applicable to the first number in the sequence (0). Of course, with it being close to Halloween, I had to have* something* with thirteen in it!

I hope you enjoyed this Halloween version of Numbers Sequence! Please let me know if you liked it or not, and I will add more (or not) based on the responses.
