What would be the next number in this series 15 12 13 10 11 8?
Each ascending number is equal to the square of the next prime number multiplied by (the prime number plus one). In this case, 11 squared x 12 = 1452. Therefore, the next number in the sequence is equal to 13 squared x (13 + 1) = 13 squared x 14 = 2366.Following this, the next number would be 17 squared x 18 = 5202.
The number 12 is important because, without the number 12, two odd numbers would be right next to each other and it wouldn't be right, because it wold go 1,2,3,4,5,6,7,8,9,10,11,13,14,15,16,17,18... and that won't be right cause there Will be one less even number so starting at 11 you would do 11/1=11 then 13/1=13 instead of 12/2=6.

Since each number is one less than the one before it, the next number would be 8.

13 is one possibility.

You can say " she will be 13 next year." or you can say "she just turned 12" or "she will be 13 soon." (I am 12 myself and that is what I would say.) :)
