Give the next few numbers in this sequence and say what the sequence is:
1, 7, 3, 58, 19, 8, 5, 10, 70, 428, 10, 70, 119, 10, 70

(In reply to A wild guess by Hugo)

This is better: Get a hammer and a nail.  Put the nail in the center of the number and hit it.

Now you can rotate the number 180°, with the nail as the center and voilą there is the same number again.
