6 3 48 3 10 4 3 1 ? 5 6
The next number in the pattern is 48. This pattern adds multiples of three to the existing number. 3 + (3 x 0) = 3 3 + (3 x 1) = 6 6 + (3 x 2) = 12 12 + (3 x 3) = 21 21 + (3 x 4) = 33 33 + (3 x 5) = 48 etc.

The answer is 5
6 3 48 3 10 4 3 1 ? 5 6
21: (3)+3=(6)+4=(10)+5=(15)+6=(21)
the answer is 72.:)
