This number sequence is cyclic. Can you find out the fifth and sixth number?

I don't get what cyclic means.

cyclic: recurring or moving in cycles

In the case of this challenge:
4-16-37-58-?-?-42-20 … goes back to the start!

So after …. 42 - 20 the sequence starts over again, to begin with 4 - 16 …..

I hope this helps.

Hi everyone,

Taking into account it is cyclic, I guess it could be some trigonometrics there. Could anyone give me a hint here? I'm a bit stuck at this challenge.

Thank you.

Can someone pm me with a hint? I've spent so much time on this one.

For all future readers: don't get caught up in the 'cyclic'-thing - it points (or has at least pointed me) into a completly wrong direction. An no, it's not a trigonometric function…
