Hey everyone!

I'd like some help on this riddle I found.

What's the next number in the pattern/sequence?

52 28 33 63 73 23 56

Any help/advice would be wonderful!

Thanks :D

Yeah, I looked at that... I'm not so sure that that would be the only approach though.

I was just wondering if anyone had any added insight.
