Help with a sequence...?

[Red]

I need some help finding the next number in this sequence. There is no suggested answer.
0,1,2,4,12,15,60

Many thanks

DD found an answer -- it's a sequence put together by a Y5 so doesn't quite "fit" verbal reasoning "rules"
her solution is: +1 x2 +2 x3 +3 x4 etc

next number is 64
