60 30 20 15 12 next in the series?

Answer 1

Each multiplication converges toward 1, starting with 1/2. So:

1/2(60) = 30

2/3(30) = 20

3/4(20) = 15

4/5(15) = 12

(n-1)/n(12) =?

The next value for 'n' is 6, thus we have:

5/6(12) = 2(5) = 10.

Answer 2

I got that one above, then saw another simple answer.

Being the sum of each of their combined numbers: -

60 = 6+0 = 6

30 = 3+0 = 3

20 = 2+0 = 2

15 = 1+5 = 6

12 = 1+2 = 3

? = 1+1 = 2

So the next lowest number is 11
