Three Two Three Sequence

What number belongs at the beginning of this sequence?

?, 3, 2, 3, 9, 2, 4, 8, 4, 3, 7, 6

3 ½.

If you break up the numbers into groups of 4, a,b,c,d, then 2 × |a – d| = |b – c|.

9 2 4 8 → 2 × |9 – 8| = |2 – 4|, or 2 × 1 = 2
4 3 7 6 → 2 × |4 – 6| = |3 – 7|, or 2 × 2 = 4, so
n 3 2 3 → 2 × |3 ½ – 3| = |3 – 2|, or 2 × ½ = 1;

I’m not sure this is the correct solution, but it’s the best I’ve found so far. Email me if you know of a better one.

What are the Things?

In one day, 6 things.
In one week, 4 things.
In one month, 2 things.
In one year, 1 thing.

What are the things?

Odd numbers.

In a day, there are 6 odd hours: 1, 3, 5, 7, 9, 11 (ignoring 24-hour time).

In a week, there are 4 odd-numbered days: 1, 3, 5, 7

In a month, there are 2 odd weeks: 1, 3 (no month has 5 full weeks)

And in a year’s 12 months, there is 1 odd number: 1 (the 1 of 12).

I readily agree the year one is a stretch, but I didn’t write it :)
